An international team of researchers has demonstrated a new way to gain a detailed understanding of what happens when two atoms meet. In their paper published in the journal Physical Review Letters, the group describes their ...
Germanene is a 2-D material derived from germanium and related to graphene. As it is not stable outside the vacuum chambers in which is it produced, no real measurements of its electronic properties have been made. Scientists ...
