Description

<jats:p> The scanning tunneling microscope (STM) can be used to select a particular adsorbed molecule, probe its electronic structure, dissociate the molecule by using electrons from the STM tip, and then examine the dissociation products. These capabilities are demonstrated for decaborane(14) (B <jats:sub>10</jats:sub> H <jats:sub>14</jats:sub> ) molecules adsorbed on a silicon(111)-(7 × 7) surface. In addition to basic studies, such selective dissociation processes can be used in a variety of applications to control surface chemistry on the molecular scale. </jats:p>
