    Interlayer sensitized van der Waals heterojunction photodetector with enhanced performance

    Although photodetection based on two-dimensional (2D) van der Waals (vdWs) P—N heterojunction has attracted extensive attention recently, their low responsivity (R) due to the lack of carrier gain mechanism in...

    Tuning the inhomogeneous charge transport in ZnO interfaces for ultrahigh on/off ratio top-gated field-effect-transistor arrays

    The interface between oxide/oxide layers shows an inhomogeneous charge transport behavior, which reveals a high conductivity owing to interface-doped. One typical example is the hetero-interface between ZnO fi...

    High-mobility junction field-effect transistor via graphene/MoS2 heterointerface

    Monolayer molybdenum disulfide (MoS2) possesses a desirable direct bandgap with moderate carrier mobility, whereas graphene (Gr) exhibits a zero bandgap and excellent carrier mobility. Numerous approaches have be...
