We have observed atomically flat gold surfaces deposited on Si (lll) 7x7 surfaces. These films are deposited by conventional evaporative deposition at a pressure below 2 X 10(-6) Pa. The surface topography was taken by scanning tunneling microscopy. Atomically flat terraces as large as 100 Angstrom separated by steps were observed. This surface should provide a good substrate for scanning tunneling microscopy studies.
