  3. Higher Quantum State Transitions in Colloidal Quantum Dot with Heavy Electron Doping

    Kwang Seob Jeong
    Electron occupation in the lowest quantized state of the conduction band (1Se) in the colloidal quantum dot leads to the intraband transition in steady-state (1Se-1Pe). The intraband transition, solely originating from the quantum confinemen...
