DOI: 10.1063/5.0021464
Abstract: The electronic work function, w(e−), and the ionic work function, w(Li+), of a lithium ultraphosphate, Li0.67PO2.8, have been measured by thermionic emission in the Richardson–Dushman regime. The values derived are w(Li+) = 1.99 ± 0.18 eV and w(e−) = 2.64 ± 0.38 eV. The measurements… read more here.
