Paper-based WS<sub>2</sub> photodetectors fabricated by all-dry techniques

Abstract

A recent application of a simple, all-dry, abrasive transfer of 2D materials on paper demonstrates the potential of two-dimensional tungsten disulfide (WS₂) as the sensitive material of a flexible photoconductive detector. The devices show really good responsivity over a bandwidth spanning from near infrared to ultraviolet and could open new avenues towards disposable optoelectronics systems.
