The MQW structure has high crystalline quality, stress difference among multiple quantum wells is reduced, and performances of the GaN-base green-light LED is improved further. Particularly, the brightness of a green-light chip is increased from 480mcd to 650mcd on the condition of 20mA, the ...
The multi- quantum well structure of the optical modulator section is a coupled multi-quantum well structure in which quantum states of the quantum wells are coupled with one another, thereby forming mini-bands. The large amounts of carriers produced by absorption are quickly scattered and lost ...
Since most of the density is in the quantum wells and only a small portion is in the barriers we scale the average input density to get the density in the quantum well and use that in the calculation of the recombination rates. There is a fitting factor mqw.qw_density_correction in ...

Despite that they appear to be electrically active, these defects turn out to have a limited effecton the dark current of these cells, which is comparable to that of the best control cells (same structure but with no quantum wells). On the other hand, the conical defects appear to be ...
The spectral response of quantum well solar cells (QWSCs) is well understood. We describe work on QWSC dark current theory which combined with SR theory yields a system efficiency. A methodology published for single quantum well (SQW) systems is extended to MQW systems in the Al(x) Ga(1-...
