Abstract

Anisotropy parabolic potential (APP) effects on ground state (GS) energy E 0 and the vibration frequency (VF) λ of weak-coupled magnetopolaron (MP) in asymmetric Gaussian quantum wells (AGQWs) were investigated using the linear combination operator and unitary transformation method. The obtained results showed that E 0 and λ were increased by increasing the barrier height V 0 of AGQWs as well as transverse and longitudinal confined strengths ω x and ω y of APP and decreased with increase in the asymmetric Gaussian confinement potential (AGCP) range R and transverse and longitudinal effective confined lengths l x and l y of APP. Thus, the GS energy and VF of MP could be changed by adjusting the confinement parameters of the APP and AGCP. The study of quantum wells' semiconductor materials has broad potential applications in semiconductor lasers, optoelectronic devices and quantum information. [ABSTRACT FROM AUTHOR]
