Abstract

Gold films were thermally evaporated in vacuum on heated cleaved mica substrates. The substrate temperature was immediately decreased after finishing the growth. Samples prepared at various temperatures from 580 K to 890 K and evaporation rates smaller than 1 nm/s were studied by a scanning tunneling microscope (STM) under ambient conditions. Structure and defects of Au(111) surfaces were investigated and discussed with respect to growth conditions.
