Abstract

Two-dimensional transition metal dichalcogenides (TMDs) are an exciting new material because of their direct band gap and semiconducting properties in the monolayer. Currently we explore different methods of synthesizing 2D MoTe2 through chemical vapor deposition (CVD). Something unique to MoTe2, in comparison to other TMDs such as MoS2, is that MoTe2 is a material that is stable in multiple phases. It consists of a semi-conductive phase known as 2H, a metallic phase known as 1T, and the 1T’ phase which is also metallic. We are focusing on growing MoTe2 and comparing any differences between the multiple phases of MoTe2. We characterize our samples through Raman spectroscopy and electrical transport measurements.
