From: Nanodevices engineering and spin transport properties of MnBi2Te4 monolayer
a Optical conductivity of MnBi2Te4 monolayer. The embedded spectrum pattern displays the visible region. b Schematic of the pin-junction phototransistor of MBT-ML. c Spin-resolved photocurrent density of Z-type pin-junction phototransistor of MBT-ML under zero bias (without power). d Gate-dependent photocurrent spectra of Z-type pin-junction phototransistor of MBT-ML under zero bias. IR, VR, and UR refer to the infrared, visible, and ultraviolet region, respectively.
