摘要: In this paper, we study the kinetics of potassium adsorption on SrTiO3(100) surface at room temperature. The took place in UHV using AES, EELS, LEED, TPD, and WF measurements. Potassium grows two-dimensional islands with maximum coverage 3.9 × 1014 at/cm2. During charge transfer from K-4s to Ti-3d energy level has been observed. No K–O compound measured. After heating 1050 K most adsorbed desorbs (1 1) LEED pattern reappears. There is not any indication intercalation into substrate, either or elevated
