Summary: Two-dimensional van der Waals heterostructures (2D vdWHs) have attracted widespread attention for their abundant and exotic properties, offering new possibilities for next-generation nanoelectronics. However, the lack of high-throughput fabrication techniques poses challenges for practical applications. In this study, a general electrochemical strategy is demonstrated to prepare high-quality vdWHs with electrostatic forces driving the stacking of individual assemblies, resulting in strong interlayer interactions. Thin-film photodetectors based on graphene/In2Se3 vdWHs show great promise for near-infrared photodetection, with high responsivity, fast rise and decay times. This approach enables the exploration of emerging electronic, photonic, and quantum phenomena.

Summary: After the emergence of graphene, the development of semiconducting organic materials with layered structures has become active in the material science field. However, these materials often face poor processability issues. In this study, a new approach is proposed to avoid the processability issue by designing a soluble amorphous network and using heat treatment to develop a flattened organic structure for organic thin-film transistors (TFTs). The fabricated TFTs exhibit good performance in both horizontal and vertical charge transport, suggesting the versatility and usefulness of this approach for the development of organic semiconductors.

Summary: Metal halide perovskites have emerged as promising candidates for next generation photodetectors due to their excellent optoelectronic properties, solution-processability and exceptional defect tolerance. However, there is a lack of reported temperature-dependent performance metrics for perovskite photodetectors, which is crucial for practical applications. This study successfully doped perovskites with trace amounts of Sn to modulate their optoelectronic properties and reduce temperature dependency. The resulting Sn-doped perovskite photodetectors exhibited high responsivity, fast response, and improved thermal stability, showing promise for real applications.

Summary: Chalcogenide-based semiconductors are highly promising for optoelectronic devices due to their low toxicity, cost-effectiveness, stability, and tunable properties. However, limited understanding of charge recombination mechanisms and trap states hinders their development. A comprehensive study on bismuth-based chalcogenide thin films was conducted to investigate the influence of post-treatments. The key findings were that post-treatment with Bi enhanced crystallinity and mobility but also increased carrier density, while post-treatment with sulfur increased carrier lifetime and mobility by passivating trap states.

Summary: Metal halide perovskites have emerged as promising candidates for next-generation optoelectronics, but the understanding of their recombination processes and trap states within devices is limited. Recent works have shown that metal cation incorporation could improve device performance, while the underlying doping mechanism is not clear. In this study, the trap-induced ultra-long carrier lifetime of metal cation incorporated perovskites was investigated, and specific cations were found to extend the carrier lifetime up to about 100 µs, which could be attributed to shallow trap states. Additionally, light-biased time-resolved microwave conductivity technique provided additional information to conventional time-resolved photoluminescence for probing the shallow trap-mediated charge dynamics.

Summary: Benefiting from excellent optoelectronic properties and easy fabrication, Sb2Se3-based semiconductor devices have gained significant attention for their decent performance in solar cells and photodetectors. However, the current focus on Sb2Se3 device research is mainly on material and device processing, with limited study on charge transport, hindering the further development of these devices. To overcome this issue, post-treatment techniques are introduced and thoroughly investigated for their influence on the charge carrier dynamics of Sb2Se3 thin films. The introduction of Se post-treatment increases the charge carrier mobility of evaporated Sb2Se3 thin films from 0.02 to 0.4 cm(2) V-1 s(-1) by an order of magnitude. Based on optimized Sb2Se3 thin films, ultra-fast photodiodes are developed, achieving a record-fast response time of 37 ns. The prototypical devices also show great potential for high-speed photodetection in practical applications.
