On the Quadron State in Parabolic Quantum Dots
Nguyen Hong Quang and Tran Anh Dung
In this work we consider a quadron - a state of four carriers - two electrons and two holes in quantum dots with parabolic confinement. By using the Hatree-Fock method,
the binding energies of the quadron and biexciton have been calculated for a full range of the electron-to-hole oscillator length ratio. The effect of the magnetic field on the binding energy of the quadron and biexciton has been also investigated. The crossing between anti-binding and
binding in both the excited quadron and biexciton states for the certain ranges of the electron-to-hole oscillator length ratio has been found .
