Summary: In this study, a bias-selectable dual-band IR detector operating at room temperature was demonstrated using lead sulfide colloidal quantum dots and black phosphorus nanosheets. By switching between zero and forward bias, the peak photosensitive range of the detector can be switched between the mid- and short-wave IR bands, with room temperature detectivities of 5 x 10(9) and 1.6 x 10(11) cm Hz(1/2) W-1, respectively. These are the highest reported room temperature values for low-dimensional material dual-band IR detectors to date.

Summary: This article introduces a semiconductor homojunction based on 2D materials, which is a promising candidate for optoelectronic logic devices. The homojunction is made from vertically stacked MoTe2/CuInP2S6/Au layers in a dual-floating gate transistor configuration. Through the band alignment between MoTe2 and CuInP2S6, the polarity of the MoTe2 homojunctions can be modulated by the floating gate, achieving logic gate XOR without the need for applied voltage. The devices also show anomalous photoresponse and optical memory behaviors, indicating their potential for fully light-actuated sensing capability in optoelectronic logic devices.

Summary: In this work, mixed-halide CH3NH3PbCl (x) Br3-x single crystal-based photodetectors with varying Cl/Br ratios were fabricated. Vertical and parallel structures devices exhibited ultranarrow spectral responses under bottom illumination, with a full-width at half-maximum less than 16 nm. The observed performance can be attributed to the unique carrier generation and extraction mechanisms within the single crystal under short and long wavelength of illumination. These findings provide valuable insights into the development of narrow-band photodetectors that do not necessitate the use of filters and have tremendous potential for diverse applications.

Summary: Conventional AI machine vision technology uses separate units for sensing, computing, and storage, leading to high power consumption and latency due to frequent data movement. A more efficient approach is using sensor elements to offload memory and computational tasks. We propose a non-volatile photomemristor that can modulate reconfigurable responsivity and store it in the device. This photomemristor implements computationally complete logic with photoresponse-stateful operations, serving as both a logic gate and memory.

Summary: This article discusses the importance and recent developments of avalanche photodiodes (APDs) in optical communication systems, as well as potential alternatives to traditional APD technologies. It shows that the evolution of APDs has led to improvements in device performance, such as higher bandwidths, lower noise, and higher gain-bandwidth products. The use of two-dimensional materials-based APDs is considered as a promising alternative due to their high-performance sensitivity and low excess noise.

Summary: This paper presents infrared detectors based on mercury cadmium telluride grown using the metal organic chemical vapour deposition technique. The design of individual areas of the heterostructure, including the absorber, contacts, and transient layers, is discussed. The paper includes examples of gain determination, current-voltage and spectral characteristics analysis, and solutions to overcome the low resistance of LWIR photodiodes by connecting multiple small individual structures in series. The performance of the HgCdTe detectors is compared with detectors based on InAs/InAsSb superlattice materials, which show comparable or superior parameters.
