Interstitial anionic electrons involved superconductivity and T-linear resistivity behavior in electride La3In
Zhijun Tu, Peihan Sun, Pengcheng Ma +7
Electrides are unique materials because of the existence of interstitial anionic electrons (IAEs). Due to these loosely bound IAEs and their strong interaction with the framework o…
