Abstract
High-quality Zn0.85Cd0.15Se/ZnSe single quantum wells (SQWs) have been fabricated on GaAs(110) crystal surfaces which were obtained by cleav ing GaAs(100) wafers in ultra high vacuum (UHV). The growth interrupti on was found to prevent the growth of high-quality quantum well struct ures. The (110)-oriented SQWs grown under appropriate conditions show a very sharp photoluminescence spectrum whose full width at half-maxim um (FWHM) is as small as 4.9 meV. The sample showed a strong in-plane polarization angle dependence of the emission intensity, due to the co mpressive strain in the well layer. The ratio of maximum to minimum va lues of the polarized PL intensity was 1.6.
