Figure 1 | Working principle of the critical BTBT memory. a, Schematic diagram of the critical BTBT memory. b, Negative photomemory characteristics of the critical BTBT memory in response to multiple 520 nm laser pulses with a duration of 500 ns. c, band alignments are depicted at Vg < 0 with a constant Vd. Only when the critical BTBT condition is satisfied, does the device exhibits negative and non-volatile photo memory characteristics.
