Fig. 1. Schematic of the MoSe2/WSe2 heterostructure. (a) W was deposited onto the SiO2/Si substrate. (b) A WSe2 film was formed via selenization. (c) Molybdenum (Mo) was deposited on the top of the WSe2. (d) A MoSe2/WSe2 heterostructure was formed via selenization. (e) The MoSe2/WSe2 heterostructure with Al electrodes.
