Shallow donors in the triple-graded quantum well under the hydrostatic pressure and external fields

Kasapoglu, E; Sari, H; Sokmen, I (ELSEVIER SCIENCE BV, 2006)

The binding energy of the donor in the triple-graded GaAs-(Ga,Al)As quantum well under the hydrostatic pressure, electric and magnetic fields are calculated by using a variational approach. The results have been obtained ...

A new approach to quantum well infrared photodetectors: Staircase-like quantum well and barriers

Eker, SU; Hostut, M; Ergun, Y; Sokmen, I (ELSEVIER SCIENCE BV, 2006)

We present a theoretical investigation of a novel staircase-like quantum well infrared photodetector (QWIP). The proposed structure makes use of quantum wells and barriers with increasing Al content both in the wells and ...
