Solution-processed thin films for electronics from single-walled carbon nanotubes and graphene:
No full textSingle-walled carbon nanotubes (SWNTs) and graphene are sp2 hybridized carbon nanostructures which exhibit extraordinary electronic properties arising from their unique energy dispersions and dimensionalities. A major issue preventing implementation of these materials into integrated electronic devices is the absence of large-scale controllable synthesis and subsequent manipulation. To circumvent this issue, solution processing of SWNTs and graphene has been proposed. Deposition of thin film networks allows the realization of a new class of materials that are useful for large-area or “macro-electronics” on flexible and inexpensive platforms.
In this thesis, controllable and efficient solution-based deposition of SWNT and graphene thin film networks and their opto-electronic properties are investigated. Topics such as material dynamics in liquid, chemical structures, defects, morphology, and doping are studied utilizing various spectroscopy and microscopy analysis along with complementary electrical measurements. Further insight is provided through demonstrations of proof-of-principle thin film transistors, organic photovoltaics, and field emitters based on solution-processed SWNT and graphene thin films.Ph.D.Includes bibliographical references (p. 134-150)by Goki Ed

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
