Description
Yolanda Manzanares-Negro and co-authors test how a two-dimensional material holds up under repeated stress, in this 2023 study. The material, MoS2, is a semiconductor sheet one atom thick, eyed for tiny moving devices. Repeated bending can crack such sheets, and missing atoms can seed the cracks, so the team added vacancies in controlled amounts and cycled the sheets.
Clean, high-quality sheets endured a billion stress cycles at eighty percent of their breaking strength, beating steel and nearing graphene. Adding the level of vacancies that large-scale making usually leaves cut the safe strength to about half the breaking point. The team also spotted a sudden reshuffle of defects just before total failure, which they name as the main wear path. The results guide how pure the sheets must be for lasting devices.
