Synthesis and characterization of MoS2 nanostructures using pulsed-laser deposition system

Nanostructures, with one or more dimensions in the lOOnm size range, exhibit a variety of unique and tunable chemical and physical properties when engineered appropriately. The high degree of variability in size and surface chemistry of nano-scale materials in coatings, crystal structure, shape and composition used in growing layered MoS2 and nanostructures increase both their complexity and the multiple permutations that must be considered in their evaluation. This project will systematically study the growth kinetics of MoS2 structures. A number of parameters such as electronic structures, surface morphology, experimental deposition conditions, will be considered in relation to the size and shape of the nanostructures. These results will be used as a criterion for determining regimes of suitable surface modification.
