Summary: Band-engineered van der Waals heterostructures are able to construct high room-temperature detectivity detectors for visible light and blackbody infrared light by blocking dark current without suppressing photocurrent. Utilizing two-dimensional materials with self-passivated surfaces and tunable band structures, unipolar barriers can be designed to avoid lattice mismatch and interface defects, achieving low dark current and high detectivity in photodetectors.

Summary: This study systematically investigates the working mechanisms of Sb2O3 and two Sb2O3-like molecules (As2O3 and Bi2O3) as dielectrics, using a combination of first-principles calculations and gate leakage current theories. It is found that molecules-based vdW dielectrics have a significant advantage over conventional materials, as defects have hardly any impact on their insulating properties. Furthermore, the study reveals that Sb2O3 faces challenges in meeting the requirements for both p-MOS and n-MOS devices, while As2O3 can serve as a dielectric for both types. This research provides a theoretical foundation for the application of molecules-based vdW dielectrics and offers a competitive choice (As2O3) for optimizing the dielectric layer in 2D vdW semiconductor-based CMOS devices, with profound implications for the future semiconductor industry.

Summary: A floating-gate memory based on van der Waals heterostructure is utilized, demonstrating a large storage window ratio (>75.5%), an extremely high on/off ratio (10^7), and an ultrafast electrical writing/erasing speed (40 ns). These enhanced performance characteristics enable excellent multilevel data storage, robust retention, and endurance performance. Stable optical erasing operations can also be achieved by illuminating the device with a laser pulse, showcasing outstanding optoelectronic storage performance (optical erasing speed >2.3 ms). The nonvolatile and high-speed characteristics of these devices hold significant potential for the integration of high-performance nonvolatile memory.
