Tunneling Desorption of Single Hydrogen on the Surface of Titanium Dioxide.

Published in ACS Nano

We investigated the reaction mechanism of the desorption of single hydrogen from a titanium dioxide surface excited by the tip of a scanning tunneling microscope (STM). Analysis of the desorption yield, in combination with theoretical calculations, indicates the crucial role played by the applied electric field. Instead of facilitating desorption b...
