概要

• 論文の詳細を見る

• We present theoretical studies on the spontaneous emission spectrum of a single self-assembled InAs/GaAs quantum dot (SAQD) embedded in a p-n junction under bias via Keldysh's non-equilibrium Green's function method. For this open system, the emission spectrum can display four coexisting peaks, corresponding to the recombination of exciton, positive and negative trions, and biexciton, even though there is only a single quantum dot. The integrated intensities of the exciton and biexciton peaks increase, respectively, linearly and quadratically with tunnelling rates.
