Restructuring of the Ge(100) surface by Na chains

First-principles study of lithium adsorption on Si(100)2×1 and Ge(100)2×1 surface at 1.0 monolayer coverage

“…Of all the alkali metals, potassium and sodium on the Si(1 0 0) and Ge(1 0 0) surface have been widely investigated experimentally and theoretically [3][4][5][6][7][8][9][10][11][12][13][14][15]. Cesium and Rubidium on the Si(1 0 0) surface also been investigated [16][17][18][19][20][21][22].…”
