- Chinese scientists developed a method for mass-producing high-quality indium selenide, a 'golden semiconductor'.
- The study was published in Science by researchers from Peking University and Renmin University of China.
- Indium selenide outperforms silicon-based technology, but large-scale production was previously challenging due to maintaining the correct atomic ratio.
- The new technique involves heating amorphous indium selenide film and solid indium under sealed conditions to produce high-quality crystals.
- The team successfully produced 5-centimeter-diameter indium selenide wafers suitable for integrated chip devices.
- This breakthrough could lead to next-generation chips for AI, autonomous driving, and smart terminals.
- Science reviewers praised the work as 'an advancement in crystal growth'.
