Recent reports have demonstrated that alloyed transition metal dichalcogenides (TMDs) can achieve a tunable band gap depending on their compositions, giving them a distinct advantage over traditional single-phased TMDs for electronics and optoelectronics.  I have successfully tuned several key growth parameters in order to improve the size and optical quality of individual alloy crystals grown by chemical vapor deposition (CVD) methods and have measured the optical properties of these alloys by Raman and photoluminescence spectroscopies.
