Electrochemical nanostructuring of n-Si(111) single-crystal faces

The local formation and dissolution of low-dimensional phases and small clu sters on foreign substrates plays an important role in modem nanotechnology . This paper deals with the current state of nanostructuring of semiconduct or surfaces by localized electrochemical metal deposition using in situ sca nning tunneling microscopy as a nano-tool. New experimental results of delo calized and localized electrochemical deposition and dissolution of Pb on n -type Si(111) single-crystal surfaces are presented. The influence of surfa ce inhomogeneities on the local metal deposition process is considered. (C) 1999 The Electrochemical Society. S0013-4651(98)05-054-X. All rights reser ved.
