For twenty years the semiconductor industry chased indium selenide, a two dimensional material with better electrical properties than silicon, and for twenty years nobody could manufacture it. A team at Peking University finally solved it, not with tighter process control, but by flooding the reaction with molten indium and letting the chemistry sort itself out. The resulting transistors switch at almost the thermodynamic limit and beat industry roadmap targets set for 2037. This video breaks down how the method works, why the AI power wall makes it matter, what it actually means for lithography and export controls, and the six limitations almost every other write-up left out.

They drowned it. 4:27 The measurements: 67 mV/dec
