Molybdenum ditelluride (MoTe2) is a member of two-dimensional (2D) transition metal dichalcogenides (TMDCs) family, which have two different stable structures: semi-metallic (2H) and metallic (1T’) phase. Theoretically, 2H-MoTe2 has direct bandgap [1] (~1.10 eV) for single and indirect bandgap [2, 3] of (~1 eV) for bulk layer respectively.
