Publikováno v: Il Nuovo Cimento D. 17:1359-1366

The optical properties of multiple quantum wells in the transition from isolated wells to a superlattice are investigated theoretically and experimentally. For superlattices with a miniband width similar to the binding energy of the 2s exciton of the

It has been recently recognized that in bulk semiconductors the displacement current caused by ultrafast optical generation of ``polarized pairs'' in the applied dc field is an important mechanism of charge transport in addition to the usual transpor

We have theoretically and experimentally studied the spin‐dependent Landau levels for electrons and holes in narrow‐gap InSb/AlInSb quantum well systems. We use the envelope function approximation for the electronic and magneto‐optical properti

Excitonic photoluminescence line shape due to interfacial quality in quantum well structures in a magnetic field

Autor: G. D. Sanders, Johngchul Lee, K. K. Bajaj

Publikováno v: Journal of Applied Physics. 69:4056-4059

We present a theory correlating the excitonic photoluminescence linewidth in quantum wells with the microscopic structure of the interface in the presence of a magnetic field. The interface is described in terms of microscopic fluctuations δ1 and δ
