Designer Entropy Enables High Thermoelectric Power and Efficiency

open access: yesInterdisciplinary Materials, EarlyView.
Designer Entropy enables targeted control of defect and transport behavior in SnTe‐based alloys, allowing efficiency and power to be independently optimized. Radius‐matched Sb doping preserves carrier mobility and delivers superior power output, while Bi‐induced disorder suppresses mobility despite comparable efficiency.

Review of millimeter‐wave and terahertz near‐field synthetic aperture radar imaging technology

open access: yesInfoScience, EarlyView.
Abstract This paper comprehensively reviews the development of millimeter‐wave (MMW) and terahertz (THz) near‐field imaging technologies, with an emphasis on the state of synthetic aperture radar (SAR)‐based imaging technologies. Near‐field imaging technologies are categorized into passive and active imaging modes, among which active imaging is favored

Perovskite‐based time‐domain signal‐balancing LiDAR sensor with centimeter depth resolution

open access: yesInfoMat, EarlyView.
In this study, we present a monolithic high‐speed perovskite‐based photodetector capable of directly sensing the time delay between two light pulses with a temporal resolution of at least 170 ps. This outstanding time resolution is achieved through a signal‐balancing detection scheme that effectively overcomes the limitations of conventional ...
