High‐Speed Photoresponse of CVD‐Grown Lateral TMD Heterostructures

Advanced Functional Materials, EarlyView.
Internal electric fields generated by p‐n junctions and asymmetric Schottky barriers enhance the photoresponse speed in CVD‐grown monolayer TMD lateral heterostructures. This results in a 1.5‐2 orders of magnitude reduction in rise and fall times for optimized device configurations compared to homogeneous single‐material devices, enabling bandwidths ...
