Carrier-capture-assisted optoelectronics based on van der Waals materials to imitate medicine-acting metaplasticity

Abstract Recently, researchers have focused on optoelectronics based on two-dimensional van der Waals materials to realize multifunctional memory and neuron applications. Layered indium selenide (InSe) semiconductors satisfy various requirements as photosensitive channel materials, and enable the re...
