CHOI, WK KIM, JH KIM, HB WHANG, CN JEONG, KH MIN, HG 2024-01-21T22:12:57Z 2024-01-21T22:12:57Z 2021-09-01 1993-12 0374-4884 https://pubs.kist.re.kr/handle/201004/145945 The Fermi contours for the surface-localized states of potassium adsorbed W(011) and the work function changes as a function of the potassium dose time are investigated using angle-resolved ultraviolet photoemission spectroscopy (ARUPS). Similar to hydrogen covered W(011), rapid attenuations of the hole-orbit states are observed for potassium adsorption. However, the electron-orbit states are not shifted to higher binding energies as much as those of hydrogen covered W(011). These results show that the Fermi contours of potassium covered W(011) are not expanded much in comparison with those of hydrogen covered W(011).
