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 ... -
Linear and nonlinear optical properties of asymmetric triple quantum wells under intense laser field
(IOP PUBLISHING LTD, 2019)For asymmetric triple quantum wells (ATQW) the linear and nonlinear optical absorption coefficient (OAC) and the optical refractive index change (ORIC) are analyzed according to the intense laser field (ILF). The obtained ... -
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 ... -
NONLINEAR TRANSITIONS IN SINGLE, DOUBLE, AND TRIPLE delta-DOPED GaAs STRUCTURES
(EDITURA ACAD ROMANE, 2017)In this study, the intersubband optical absorption coefficient and the refractive index change in single, double, and triple delta-doped GaAs structure will investigate for the uniform doping distribution model. The ...
