Effect of magnetic fields on the linear and nonlinear intersubband optical absorption coefficients and refractive index changes in square and graded quantum wells
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2010)
In this study, both the intersubband optical absorption coefficients and the refractive index changes as dependent on the magnetic field are calculated in square and graded quantum wells. Our results show that the position ...
Linear and nonlinear optical properties in a semiconductor quantum well under intense laser radiation: Effects of applied electromagnetic fields
(ELSEVIER SCIENCE BV, 2012)
In this work we are studying the intense laser effects on the electron-related linear and nonlinear optical properties in GaAs-Ga1-xAlxAs quantum wells under applied electric and magnetic fields. The calculated quantities ...
Magnetic-field effect on the diamagnetic susceptibility of hydrogenic impurities in quantum well-wires
