The aim of this research is to build single-electron |
| transistors (SETs) in semiconductor materials. | |
| Nanoelectronic devices can be realized in | |
| silicon-on-insulator (SOI) materials, in which | |
| we have created sub-10 nanometer SETs, | |
| also termed quantum dots, operating from | |
|
low temperatures up to 300 Kelvin. |
|
| For investigating quantum computing we are | |
| building quantum dots using Gallium- | |
| Arsenide heterostructures (GaAs/AlGaAs). | |
| Coupled quantum dots can be understood | |
| as artificial molecules which have properties | |
| similar to real molecules, but with the | |
| advantage that the artificial molecule's | |
| potentials are tunable. Thus we can create | |
| and address molecular like modes, being | |
| understood as quantum bits. | |
