Description:
A three-dimensional rendering of an ultra-high vacuum scanning tunneling microscope (STM) image of individual 2, 2, 6, 6-tetramethyl-1-piperidinyloxy (TEMPO) molecules on a Si(100) surface. The STM tip, which is used to address individual TEMPO molecules, is also schematically depicted. Room temperature STM charge transport measurements reveal negative differential resistance (NDR) through individual molecules that can be controlled through substrate doping. Representative current-voltage curves that clearly show NDR make up the background tiles.
