| Research Abstract |
Quantum optics and spins were studied in artificial atoms, such as quantum dots and isoelectric traps. The largest binding energy of biexcitons in quantum dots in the near infrared region, spin precession of excitons and electrons in charge tunable InP quantum dots, initialization process of electron spins in InP quantum dots, sign of electron g-factor in CdTe quantum dots, electron-Mn spin interaction in CdMnTe quantum dots, atomic configuration of isoelectronic trap pairs in GaP:N and quantum nature of photons in GaAs:N were revealed.
