摘要
InAs and InGaAs quantum dots were prepared by MBE onto GaAs substrates. Quantum dots size was found to be 40-50 nm in diameter and 4-7 nm in height by AFM. PL peak of InAs quantum dots is at 980 nm, and at a shorter wavelength for InGaAs dots. Composite InAs/InGaAs quantum dots should give a wider spectral response in solar cell applications. Stabilized performance of quantum dots structure at high temperatures is an attractive feature. A possibility to store photo-generated carriers in the composite structure is another important prospect.
