乌克兰第一副总理兼能源部长：今天，乌克兰在“乌克兰基金”框架下获得28亿欧元资金。高度赞赏欧盟决定为乌克兰冬季准备工作拨款9.2亿欧元，期待该决定能够迅速付诸实施。

Researchers at the Institute of Metal Research, Chinese Academy of Sciences, led by Sun Dongming and Liu Chi with multiple collaborators, reported the first silicon–graphene–germanium barrier transistor to undergo RF testing. Published in Nature Communications on June 6, the device set a record for cutoff frequency among vertical 2D-base transistors, with an intrinsic cutoff frequency (fT) of 132 GHz in RF measurements and a world‑high transistor current gain. Device modelling and simulation indicate that, with optimized doping, lower contact resistance and reduced parasitics, the theoretical operating frequency could exceed 1 THz and reach the terahertz band.
