TL;DR: The combination of high-quality Al2 O3 dielectric and thiol chemistry passivation can effectively reduce the density of interface traps and Coulomb impurities, leading to a significant improvement of the mobility and a transition of the charge transport from the insulating to the metallic regime.

TL;DR: In this paper, the fabrication of 2D molecular single-crystal semiconductors with precise layer definition by using a floating-coffee-ring-driven assembly is presented, where bilayer molecular films exhibit singlecrystalline features with atomic smoothness and high film uniformity over a large area; field effect transistors yield average and maximum carrier mobilities of 4.8 and 13.0 cm2 V−1 s−1, respectively.

TL;DR: A new hybrid structure that marries CsPbX3 IPQDs to silicon nanowires (SiNWs) radial junction structures to achieve ultrafast and highly sensitive ultraviolet (UV) detection in solar-blind spectrum is reported, paving the way toward large area manufacturing of high performance Si-based perovskite UV detectors in a scalable and low-cost procedure.

TL;DR: The use of supercritical carbon dioxide-assisted rapid synthesis of few-layer BP is demonstrated and a non-enzymatic hydrogen peroxide (H2O2) sensor is constructed for the first time to utilize BP degradation under ambient conditions.

TL;DR: An on-chip polarimeter comprising four metasurface-integrated graphene-silicon photodetectors is reported, ideal for a variety of polarization-based applications including biological sensing, quantum information processing, and polarization photography.
