Stretching the possibilities: Bendable single-crystalline diamonds hold potential for next-generation electronics

By Lisa McDonald / January 15, 2021

Diamonds have many desirable properties for application in electronic devices, but their rigid crystalline structure and brittle nature make it difficult to use diamonds for such a purpose. An international team of researchers led by City University of Hong Kong revealed in 2018 that diamonds are bendable on the nanoscale, and a follow-up paper published by them this month expands on that finding.
