Surface properties of SmB6 from x-ray photoelectron spectroscopy

We have investigated the properties of cleaved SmB\(_6\) single crystals by x-ray photoelectron spectroscopy. At low temperatures and freshly cleaved samples a surface core level shift is observed which vanishes when the temperature is increased. A Sm valence between 2.5 - 2.6 is derived from the re...
