Description | Using a scanning tunnelling microscopy (STM) technique we have shown that single molecules attaching and detaching can be detected via the conductance of a metal - molecule - compound semiconductor junction. We have shown how the choice of molecule modifies the rectifying properties of the junction and provide new knowledge concerning charge flow in such junctions at the single molecule level. This fabrication of metal - molecule - compound semiconductor junctions opens a new route to integrating devices, such as sensors, incorporating a small number of molecules and conventional semiconductor technology. We have further shown that metal - few molecule - compound semiconductor junctions generate a photocurrent that depends on both the choice of molecule and the doping density of the semiconductor, and have provided a qualitative explanation of this dependence. The photocurrent shows transient effects, which we explain as due to hole-trapping. We have also shown that molecular junctions with nickel contacts can respond to both electrical and chemical stimuli simultaneously, which is extremely important for sensor applications. |
Exploitation Route | Our work will further the development of new, ultrasensitive and ultracompact sensors. The transient photo-response detected could form the basis of a new local probe of the electronic structure of molecule-semiconductor junctions. |
