High Pressure Drives 13-Fold Enhancement and Precise Control of Terahertz Emission in Layered GaTe

A new study published in Laser & Photonics Reviews demonstrates that high pressure can significantly boost and precisely tune terahertz (THz) radiation from the two-dimensional semiconductor gallium telluride (GaTe). Using a diamond anvil cell, researchers achieved a 13-fold enhancement in THz emission and directly uncovered the sequence of ultrafast processes that generate THz waves.

New Framework Integrates ICESat-2 and Multi-Source Remote Sensing for High-Precision Bathymetric Mapping

A research team led by Prof. NIE Sheng at the Aerospace Information Research Institute, Chinese Academy of Sciences (AIRCAS), has developed a new bathymetric mapping framework that integrates indirect inversion of ICESat-2 satellite LiDAR data with multi-source remote sensing observations. The framework, detailed in Remote Sensing of Environment combines wave-based indirect bathymetry, multi-source feature fusion, and a temporal sample-transfer strategy to achieve high-accuracy, wide-coverage mapping in optically complex shallow waters.
