Electric field effect on the intersubband optical absorption of GeSn quantum wells with parabolically graded barriers
(Publisher name SPRINGER HEIDELBERG, 2023)
In this study, we propose a theoretical simulation of a Ge0.9Sn0.1 rectangular SQW with GeSn
parabolically graded barriers (PGBs) in the terahertz (THz) region. The discrete intra-band
confined energy levels and their ...
Nonlinear optical properties of modified Möbius squared potential well: influence of electric and magnetic fields
