Valence band dispersions of single-crystalline SnS1-xSex solid solutions were observed using ARPES, and the hole effective masses were directly evaluated. It was found that the hole effective masses decrease slightly with increasing Se content in the low Se composition range, but sharply in the high Se composition range.
Valence band dispersions of single-crystalline SnS1-xSex solid solutions were observed by angle-resolved photoemission spectroscopy (ARPES). The hole effective masses, crucial factors in determining thermoelectric properties, were directly evaluated. They decrease slightly with increasing Se content in the low Se composition range but sharply in the high Se composition range.
