Work function of LaB6

By means of Richardson plots, low work functions of 2.3–2.4 eV have been measured for three cyrstal planes including (100) of single‐crystal LaB6. Modifying Smith’s model of a metallic surface, the work function of LaB6 has been theoretically estimated for a jellium model at 2.31±0.05 eV which is in good agreement with experimental values.
