▎ 摘　　要

NOVELTY - The device has a substrate (10) whose surface is formed with a groove. The groove is provided with a gate (20). A first graphene layer (50) is covered on an opening position of the groove. A metal structure layer (70) is provided with multiple metal structure units. A memory alloy layer (60) is provided with multiple memory alloy units. Multiple memory alloy units are arranged on a side of the first graphene layer far away from the substrate. Multiple memory alloy units are arranged on a side of the metal structure unit far away from the substrate. A second graphene layer (80) is arranged on a side of the memory alloy units. USE - Dynamic control circular dichroism device. ADVANTAGE - The device changes shape of the first graphene layer and the second graphene layer so as to change carrier density and conductivity in the first graphene layer and the second graphene layer, so that output voltage of a device electrode is changed. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of device for dynamically regulating circular dichroism based on memory alloy.
