Intersubband electron transition across a staircase potential containing quantum wells: light emission
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005)
We present a theoretical investigation of a novel staircase-like light emitter based on the GaAs/GaxAl1-xAs material system. The emission wavelength is around 12 mum. The device operation is based on the intersubband ...
A new approach to quantum well infrared photodetectors: Staircase-like quantum well and barriers
(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 ...
