Fig. 2: Electrical characterization of α-In2Se3 FSMJ devices.

a, b Representative I-E curves for 2H and 3R α-In2Se3 FSMJ devices with Au electrodes. c, d Representative I-E curves for α-In2Se3 FSMJ devices with Ag electrodes. The Inset shows the schematic diagram of the corresponding device. e Band diagrams illustrating the FSMJ in different resistance states as observed in the I-E curves. f Band diagrams of 2H and 3R α-In2Se3 FSMJ devices at the bottom α-In2Se3/metal interface.
