| 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. |

| Description | The project has provided new strategies to incorporate radical (open shell) compounds in single-molecule devices. The project has not yet had any economic or societal impact, but has important implications towards enabling technologies such as molecular spintronics and molecular thermoelectrics, operating under ambient temperature and normal environmental conditions. This represents fundamental research which demonstrates integration of radical character, transistor-like switching, and rectification in a single molecular component. This paves the way to further studies of the electronic, magnetic, and thermoelectric properties of open-shell species and their future integration into device platforms. |
