| Outline of Final Research Achievements |
We investigated the basic physics of energy dissipation and develop some elemental techniques towards precise control of phonon in nanoscale silicon. We for the first time observed the electron-hydrodynamic effects in silicon, and demonstrated that the phonon emission is possible to prevent, resulting in the current amplification with an extremely small energy dissipation. In addition, we clarified the role of dopants during in the electron-hole recombination process. We also clarified relationship between the phonon emission and the dopant clusters in nano-scaled tunnel diodes.
