New superconductor Li(x)Fe(1+δ)Se (x ≤ 0.07, T(c) up to 44 K) by an electrochemical route
The superconducting transition temperature (T(c)) of tetragonal Fe(1+δ)Se was enhanced from 8.5 K to 44 K by chemical structure modification. While insertion of large alkaline cations like K or solvated lithium and iron cations in the interlayer space, the [Fe(2)Se(2)] interlayer separation increase...
