| Outline of Final Research Achievements |
A basic technology has been developed with a view to observing exciton quantum condensation (superfluidity phenomenon) in silicon transistors, which is particularly important for electronics applications. We have succeeded in forming electrons and holes co-existing system by controlling the gate of a silicon transistor at low temperatures. Analysis of the recombination current generated in the transistor revealed that the electrons and holes are in extremely close proximity. Direct observation of the recombination processes suggests the formation of excitons, which is important in quantum condensation.
