Electron capture process in GaAs/AlAs spherical quantum dot-quantum well structure is studied theoretically. The capture rate in two polar-optical-phononmediated capture processes has been calculated by taking into account the phonon confinement effect. Carrier capture is shown to proceed with rates as high as 1010 s–1 at temperature T>100 K. A short capture time is also achieved for low carrier density.
