A Newly Commissioned Work for Cello, A Recording and Performance Practice Guide by Yu-Ting Tseng
No full textabstract: The introduction of a new instrumental piece—specifically Taiwanese—into the cello repertoire is as exciting as it is important. Currently, the majority of works for cello and piano include predominantly Western compositions that is repeatedly taught and performed. Reflections, by Taiwanese composer Ming-Hsiu Yen (Ms. Yen) is a response to this saturation. It is a piece that is both demanding for the performers and entertaining for the audience. Brilliantly written by a composer who has intimate familiarity with both the cello and piano, it is highly suitable for scholarly study and performance.
This document details ensemble issues, interpretative suggestions for both cellist and pianist, and general concepts about the music. The composer further adds to these concepts and suggestions.
Reflections is a programmatic work comprised of four movements, each with a descriptive title: “Gear,” “Tears of the Angel,” “Spintop,” and “Transformation.” Because the composer’s intentions were driven by pictorial ideas and not by a formal harmonic structure, this paper concentrates on ensemble issues and interpretation less than harmonic analysis.
Secondly, the project includes the premiere recording of Reflections, as performer by Yu-Ting Tseng, cellist, and Dr. Jeremy Peterman, pianist. This audio documentation provides other cellists and pianists the opportunity of hearing the piece as originally conceived by the composer, as an aid to their own future preparation of this work. This recording, combined with the interpretative analysis, will assist in bringing Reflections into the cello repertoire and public eye.Dissertation/ThesisReflections Recording Movement I GearReflections Recording Movement II Tears of the AngelReflections Recording Movement III SpintopReflections Recording Movement IV TransformationDoctoral Dissertation Music 201

No full textDesign and modeling of high speed P-i-N photodetector for 50 GB/S optical fiber links
No full textHigh speed optical interconnect holds the key to the future Internet revolution; optical fibers have replaced traditional copper wires over long distances within data centers and high performance computing (HPC) due to their speed and reliability. With the increasing demand for high speed data transmission in data center and cloud computing applications, the development of optical transceivers has become indispensable. To complement high speed transmitters in optical links, high speed receiver devices, known as photodetectors, need to be designed properly so as not to present a bottleneck in the performance of optical links. With the aid of microwave modeling, we can characterize the performance of the photodetector and therefore improve the devices. This work will present the quantitative design and analysis of the P-i-N photodetector which is capable of operating at 50 Gb/s data rate for energy efficient transmission.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2019-08-01The student, Yu-Ting Peng, accepted the attached license on 2017-07-05 at 16:23.The student, Yu-Ting Peng, submitted this Thesis for approval on 2017-07-05 at 16:30.This Thesis was approved for publication on 2017-07-06 at 10:03.DSpace SAF Submission Ingestion Package generated from Vireo submission #11315 on 2017-09-29 at 10:46:42Made available in DSpace on 2017-09-29T17:45:22Z (GMT).

No full text Wide bandgap gallium nitride material has highly favorable electronic properties for next generation power and high frequency electronic devices. A less widely studied application is highly miniaturized chemical and gas sensors capable of operating in harsh environment conditions. In this work we present our recent developments on design, fabrication and testing of AlGaN/GaN high electron mobility transistor (HEMT) based sensors for detection of various gases. First, the method of as-fabricated device baseline value stabilization is demonstrated. Secondly, the impact of sensor design is discussed with the emphasis on gate electrode geometry optimizations to enhance sensing performance. Then we present the sensing characteristics of Pt-HEMTs towards H 2 S and compare them to H 2 and NO 2 . Finally we demonstrate recent results of NO 2 detection with Ti/Au based HEMT sensors, which are superior to those using Pt based devices.

Development of InP DHBT for 5G millimeter-wave power amplifier and GaAs photodetector for 50 Gb/s optical link
No full textThe high-speed optical transceivers require high-speed photodetector to be paired with high-speed vertical-cavity surface-emitting lasers (VCSELs) for short-range transmission at 850 nm. High-speed photodetector holds the key to higher data rate and lower energy consumption, which can help resolve the rising data traffic with high power efficiency. As for wireless communication, Indium phosphide (InP) heterojunction bipolar transistors (HBTs) are widely deployed in high-speed mixed signaling and radio-frequency (RF) instruments because of their outstanding ability to amplify the signals at high-speed bandwidth. Moreover, inherent material properties of InP such as high durability of the breakdown field and fast electron drift velocity make this material one of the suitable candidates when it comes to power amplifier applications within millimeter-wave spectrums. In this work, the development of the 50 Gb/s P-i-N photodetector Type-II InP DHBT for 5G power amplifier application will be presented and discussed. The development work of the photodetector includes the design consideration and process optimization, the dark current and bandwidth characterization of the fabricated device, followed by the impulse response measurement and microwave modeling. The development of Type-II InP DHBT consists of the review of the previous InP DHBT works at UIUC, plasma-enhanced InP dry-etching process development, DC and small-signal characterization, physical parameter extraction and ADS microwave modeling.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2023-08-01The student, Yu-Ting Peng, accepted the attached license on 2021-06-30 at 19:00.The student, Yu-Ting Peng, submitted this Dissertation for approval on 2021-06-30 at 19:20.This Dissertation was approved for publication on 2021-07-01 at 17:47.DSpace SAF Submission Ingestion Package generated from Vireo submission #16741 on 2022-01-12 at 12:52:48Made available in DSpace on 2022-01-12T22:34:50Z (GMT).
