- The atomic structure and morphology of ultrathin Pb layers deposited on the Ni(001) face in ultrahigh vacuum at the substrate temperature, ranging from 145 K to 900 K, were investigated with the use of the Auger electron spectroscopy and low-energy electron diffraction. The analysis of the Auger electron spectroscopy measurements indicates that the Volmer-Weber growth of the Pb takes place for substrate temperature T < 300 K. Between 300 and 600 K, the Stranski-Krastanov growth mode is observed. For 600 K ≤ T ≤ 700 K, only first two-dimensional Pb layer formation is found. Above 700 K desorption of lead atoms from the first layer is observed. The ordered low-energy electron diffraction patterns corresponding to p(1×1) and c(2×2) structures are observed.
