Nanowerk  November 28, 2022 Researchers in Austria bombarded ultrathin materials with highly charged ions to explain why sometimes the projectile penetrates the material layer without any noticeable change in the material and sometimes the material layer around the impact site is also completely destroyed. They found that it is not the momentum of the projectile that is mainly responsible for the holes, but its electric charge. When an ion with multiple positive charge hits the material layer, it attracts a larger number of electrons and takes them with it leaving a positively charged region in the material layer. Graphene’s high […]
