Design and analysis of transition metal dichalcogenide-based feedback transistor
No full textA rise in short channel effects (surface scattering, drain lowering, carrier injection, etc.) in a metal oxide semiconductor field-effect transistor (MOSFET) is worrisome for researchers. Alternate solutions by researchers are tunnel FETs (TFETs), junctionless transistors, and nanowires. Due to random dopant fluctuations, TFETs suffer from various disadvantages like fabrication issues and higher miller capacitances. Junctionless transistors and nanowires do not have fabrication issues but face poor short channel control.
Another major unsettled domain is the choice of channel material as silicon suffers significantly in the nanometer regime. Two-dimensional (2D) materials like graphene, transition metal dichalcogenides (TMDCs), and black phosphorus (BP) have provided a solution. Graphene has charge carriers with high mobility, but proposed devices suffer from poor OFF-state current due to the semimetal bandgap of graphene. Although with proper fabrication technique the bandgap can be introduced in the graphene layered structure, it hampers the mobility of charge carriers. In case of BP, mobility increases with an increase in the number of layers, which act as a bottleneck for small-scale devices.
In this work, the TMDC material-based feedback field-effect transistor is proposed and analyzed. The feedback transistor provides a steep rise in drain current (IDS ), which provides a very low subthreshold slope; hence, it can be used for high-speed applications. Molybdenum ditelluride (MoTe2) is used as a channel material as it has the lowest bandgap among the TMDC materials, which further aids in high-speed applications. Different device and linearity properties for the proposed device are inspected
Design and analysis of dopingless charge-plasma-based ring architecture of tunnel field-effect transistor for low-power application
No full textThis chapter discusses the dopingless charge-plasma-based ring architecture of the tunnel field-effect transistor (CP-Ring-TFET). The operation of the TFET has been described in this chapter. The two- and three-dimensional structures of the CP-Ring-TFET with device specification are also described. For a simulation of the device, the Silvaco technology computer-aided design (TCAD) tool is used. This chapter also covers the methodology, device specification, and model specification used in the simulation of the CP-Ring-TFET device. The proposed CP-Ring-TFET device is a dopingless device and CP technique is used to operate the proposed device in the equilibrium operating region, OFF operating region, and ON operating region. For the performance analysis of the CP-Ring-TFET device, various parameters are examined like device and analog specification. The proposed CP-Ring-TFET structure shows the higher ON-state current (ION ), better subthreshold slope (SS), and lower threshold voltage (VTH ), which is beneficial for low-power applications
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Critical insights from recent outbreaks of Mycoplasma pneumoniae: decoding the challenges and effective interventions strategies
No full textOBJECTIVES: Mycoplasma pneumoniae (M. pneumoniae) continues to pose a significant disease burden on global public health as a respiratory pathogen. The antimicrobial resistance among M. pneumoniae strains has complicated the outbreak control efforts, emphasizing the need for robust surveillance systems and effective antimicrobial stewardship programs.DESIGN: This review comprehensively investigates studies stemming from previous outbreaks to emphasize the multifaceted nature of M. pneumoniae infections, encompassing epidemiological dynamics, diagnostic innovations, antibiotic resistance, and therapeutic challenges.RESULTS: We explored the spectrum of clinical manifestations associated with M. pneumoniae infections, emphasizing the continuum of disease severity and the challenges in gradating it accurately. Artificial intelligence and machine learning have emerged as promising tools in M. pneumoniae diagnostics, offering enhanced accuracy and efficiency in identifying infections. However, their integration into clinical practice presents hurdles that need to be addressed. Further, we elucidate the pivotal role of pharmacological interventions in controlling and treating M. pneumoniae infections as the efficacy of existing therapies is jeopardized by evolving resistance mechanisms.CONCLUSION: Lessons learned from previous outbreaks underscore the importance of adaptive treatment strategies and proactive management approaches. Addressing these complexities demands a holistic approach integrating advanced technologies, genomic surveillance, and adaptive clinical strategies to effectively combat this pathogen.</p
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
