Abstract

A mid-infrared orbital angular momentum detector based on multilayer graphene has been successfully developed, overcoming the previous reliance on C point group topological Weyl semimetals via the orbital photogalvanic effect. This CMOS-compatible two-dimensional material system is crucial for advancing the large-scale practical application of orbital angular momentum detectors.

摘要

一种基于多层石墨烯的中红外轨道角动量探测器已成功研制出来，通过轨道光电流效应克服了以往对C点群拓扑外尔半金属的依赖。这种与CMOS兼容的二维材料系统对于推动轨道角动量探测器的大规模实际应用至关重要。
