摘要：
InAs/InP quantum well structures with an epitaxially controlled amount of island growth are investigated by excitation spectroscopy and magnetoluminescence. From the diamagnetic shift of the luminescence, an approximate value of the exciton radius is obtained. The very small lateral radius of below 6 nm is evidence of reduced dimensionality and lateral confinement effects.
