Tunable Electronic And Optical Properties Of Low-Dimensional Materials, Shiyuan Gao
Tunable Electronic And Optical Properties Of Low-Dimensional Materials, Shiyuan Gao
Arts & Sciences Electronic Theses and Dissertations
Two-dimensional (2D) materials with single or a few atomic layers, such as graphene, hexagonal boron nitride (h-BN) and transition metal dichalcogenides (TMDCs), and the heterostructures or one-dimensional (1D) nanostructures they form, have attracted much attention recently as unique platforms for studying many condensed-matter phenomena and holds great potentials for nanoelectronics and optoelectronic applications. Apart from their unique intrinsic properties which has been intensively studied for over a decade by now, they also allow external control of many degrees of freedom, such as electrical gating, doping and layer stacking. In this thesis, I present a theoretical study of the electronic and …
Synthesis And Drop-On-Demand Deposition Of Graphene Derivative Inks For Flexible Thin Film Electronics, Dogan M. Sinar
Synthesis And Drop-On-Demand Deposition Of Graphene Derivative Inks For Flexible Thin Film Electronics, Dogan M. Sinar
Electronic Thesis and Dissertation Repository
This dissertation presents methods for deposition and post-processing of Graphene-Carboxymethyl Cellulose (G-CMC) and Graphene Oxide (GO) aqueous functional inks using a custom drop-on-demand (DOD) printer to fabricate mechanically flexible, non-transparent and transparent thin film electronic devices. Thin films on flexible substrates find use in lightweight, low profile, and conformable electronic devices. Such devices can include chemical sensors, flexible RFID tags, bioelectronics circuits, lightweight electronics for space systems, and transparent electrodes for optoelectronic systems. The goal of this research project is to provide simple methods for fabrication of these devices using environmentally friendly and easy to synthesize functional inks. Therefore, two …
