| dc.title | Alkali Displacements in Intercalated 1T-TaSe(2) | en |
| heal.abstract | Single crystals of 1T-TaSe(2) have been intercalated with different alkali metals by deposition in ultra-high vacuum onto in situ-cleaved (0001) surfaces. In a second step a different alkali metal, or Cl(2), has been deposited on top. The interactions among the deposited species and the substrate have been investigated using soft x-ray photoelectron spectroscopy (SXPS). Li and Na appear to compete in the intercalation process. Li replaces Na, by pushing it deeper into the crystal. Cs on Li:TaSe(2) does not intercalate, but stays on top, repelling intercalated Li(+) deeper inside. For Li on Cs:TaSe(2) an exchange reaction takes place, and Cs is deintercalated. The same effect is induced by Na deposited on intercalated Cs. 1T -> 2H phase transition for TaSe(2) has been observed only for Li deposition. Cl(2) deposition on Na intercalated substrate induced deintercalation of Na. The experimental results are discussed in relation to thermodynamic, electronic and electrostatic effects. | en |
