Broadband staircase quantum well infrared photodetector with low dark current
(ELSEVIER SCIENCE BV, 2006)We present a theoretical investigation of a novel staircase-like quantum well infrared photodetector (QWIP). It detects wavelengths between 8.8 mu m and 12.3 mu m at an applied electric field of F= 6 x 10(4) V/cm at room ... -
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 ...
