Quadrupole second harmonic generation and sum-frequency generation in ZnO quantum dots
The second harmonic generation (SHG) and the sum frequency generation (SFG) processes are investigated in the conduction band states of the singly charged ZnO quantum dot (QD) embedded in the HfO2, and the AlN matrices. With two optical fields of frequency ωp and ωq incident on the dot, we study the...
