Abstract

Abstract: The conducting properties of two organic thiols (5-mercapto-2, 2'-bithiophene and 4-mercaptobiphenyl) deposited by the self-assembly method on Pt tips have been characterized in ultrahigh vacuum by field emission microscopy and spectroscopy. It was shown that these two molecular species can be successfully adsorbed from solution on the Pt tip. The presence of the molecules causes a large decrease in the required field ...
