The effect of intense laser field on the photoionization cross-section and binding energy of shallow donor impurities in graded quantum-well wire under an electric field
(IOP PUBLISHING LTD, 2006)
The laser-field dependence of the impurity binding energy and donor-related photoionization cross-section in graded quantum-well wire under an external static electric field is calculated by a variational method and in the ...
Shallow donors in a coupled triple graded quantum well under the electric and magnetic fields
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2006)
The binding energy of the donor in three different shaped triple graded GaAs-(Ga, Al)As quantum wells which is obtained by changing the depth of the central-well potential (V-o) is calculated by using a variational approach. ...
Intersubband optical absorption in double quantum well under intense laser field
(EDP SCIENCES S A, 2006)
The intersubband absorption in symmetric double quantum wells under the laser field is theoretically calculated within the framework of the effective mass approximation. Results obtained show that intersubbband optical ...
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 ...
