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 ...

Exchange‐Coupled Two‐Dimensional MOFs

Advanced Functional Materials, EarlyView.
Graphene mediates ferromagnetic coupling between two‐dimensional metal‐organic frameworks and cobalt. Fe‐tetracyanobenzene develops a remanent magnetic response whose orientation follows the cobalt magnetization direction and persists up to room temperature, whereas Ni‐TCNB remains only field‐polarized.
