In a 2D monolayer of aluminium hydride (AlH2), excess anionic electrons provided by the aluminium are confined in the interstices of the aluminium lattice. Applying strain changes this electron configuration and raises the critical temperature for superconductivity. (Courtesy: Z Zhao)
A new theoretical study sheds fresh light on the relationship between superconductivity and “exces
