摘要：
The Stark shifts in semiconductor microcrystallites CdS0.12Se0.88, CdSe and GaAs are investigated by the variational calculations including the Coulomb interaction and the polarization energy. It is found that the Coulomb interaction plays a significant role even in microcrystallites with radii as small as one third of the Bohr radius of the exciton. © 1990.
