Fabrication of Gas Nanosensor based on 2D Nanostructure Titanium trisulfide/Graphene Heterojunction, Ph.D. Dissertation Sharif University of Technology ; Iraji Zad, Azam (Supervisor) ; Sasanpour, Pezhman (Supervisor) ; Esfandiar, Ali (Co-Supervisor)
Abstract
Titanium trisulfide (TiS3), a transition metal chalcogenide, bears the potential to replace silicon, when taking the form of nanoflakes, due to its favorable band gap and optical response. In this work, first we investigate the response of TiS3 nanoflakes to gas detection through a careful quantum computational approach and a few succinct measurements. The computations are benchmarked and compared with a relevant experiment at each step, where their results/conclusions are discussed. The most stable surface of TiS3 particles is determined to (001), in agreement with the literature. The adsorption of 5 gas molecules is characterized through formulating and estimating their adsorption...
