Dynamic circular dichroism regulation and control device and system based on memory alloy

Abstract

The invention relates to a dynamic circular dichroism regulation and control device and system based on memory alloy, in particular to a circular dichroism regulation and control system. The dynamic regulation circular dichroism device based on the memory alloy comprises a substrate, a grid electrode, a source electrode, a drain electrode, a first graphene layer, a second graphene layer, a memory alloy layer and a metal structure layer. When the device needs to be regulated, the external environment of the device is changed, and then the memory alloy layer is deformed, so that the shapes of the first graphene layer and the second graphene layer are changed, the carrier density and conductivity in the first graphene layer and the second graphene layer are changed, the output voltage of the electrode of the device is further changed, and when circular dichroism signals are irradiated by left-hand circularly polarized light and right-hand circularly polarized light respectively, the output voltage difference of the device is related, that is, the circular dichroism signal of the device is changed by changing the output voltage of the device.
