ABSTRACT
The preparation of n-MoSe2/p-WSe2 heterojunctions by epitaxial growth of WSe2 (Eg=1.16 eV) on MoSe2 (Eg=1.06 eV) substrates is reported. The two semiconductors are nearly lattice matched along their hexagonal (001) base plane with Δa/a=0.25%. Diode capacitance-voltage measurements show that the band edges of MoSe2 and WSe2 are aligned within ∼0.1 eV. The diode forward current at room temperature is carried by recombination in the depletion region.
