Summary: This study reports the use of large-area liquid-metal-printed ultrathin Ga2O3 dielectrics for 2D electronics and optoelectronics. The conformal nature of liquid metal printing enables atomically smooth Ga2O3/WS2 interfaces. The compatibility of atomic layer deposition with Ga2O3/HfO2 top-gate dielectric stacks on monolayer WS2 is demonstrated, achieving small equivalent oxide thicknesses and subthreshold swings. These results show that liquid-metal-printed oxides can fill a crucial gap in dielectric integration of 2D materials.

Summary: High-resolution imaging is crucial for intelligent technologies and is important for extracting and storing high-sensitivity information. However, the development of ultrabroadband imaging is hindered by the incompatibility between non-silicon optoelectronic materials and traditional integrated circuits, as well as the lack of competent photosensitive semiconductors in the infrared region. In this study, wafer-scale tellurene photoelectric functional units are monolithically integrated through room-temperature pulsed-laser deposition. The tellurene photodetectors demonstrate wide-spectrum photoresponse and unprecedented photosensitivity, enabling the realization of ultrabroadband imager and high-resolution photoelectric imaging.

Summary: Driven by the rapid development of autonomous vehicles, ultrasensitive photodetectors with high signal-to-noise ratio and ultraweak light detection capability are urgently needed. However, the lack of an effective photoconductive gain mechanism in individual indium selenide (In2Se3) inhibits its further application. To address this issue, a heterostructure photodetector is proposed, consisting of an In2Se3 photoactive channel, a hexagonal boron nitride (h-BN) passivation layer, and a CsPb(Br/I)(3) quantum dot gain layer. This device demonstrates excellent performance characteristics and has potential applications in autonomous vehicles.
