2D PtTe2 Layers Synthesized by Thermally Assisted Conversion Method

Scalable production and controlled doping of large-area two-dimensional transition-metal dichalcogenide films are fundamental steps toward their applications in electronic and opto-electronic devices. Although a variety of methods for preparation of wafer-scale transition-metal dichalcogenide films have been developed, they still need further elaboration to satisfy the high quality requirements for application-grade materials. Here we report the synthesis of 2D PtTe2 by direct tellurization of pre-deposited thin Pt film of various thickness on soda lime glass substrates.
