Abstract

In this study, we showcase the innovative application of Orbital Angular Momentum (OAM) beams for precise manipulation of 2D material structures, emphasizing spatial and temporal control. Focusing on graphene and WS2, we illustrate the efficacy of OAM beams in manipulating the materials electrical properties. Additionally, we present a device—an optically controlled graphene Field-Effect Transistor (FET)—as a prime example of the practical implementation of this technique, highlighting its potential in advancing the field of optoelectronics and material science.
