摘要
The polaronic corrections to the electron energy and effective mass are calculated taking the Rashba spin-orbit coupling in the compositionally asymmetric single quantum well based on heterostructures of narrow gap semiconductors InGaAs and InAs. The electron interaction with the confined longitudinal optic phonon is considered in the Frohlich form for calculating the polaron properties. In the weak coupling limit, the polaron properties are enhanced by the Rashba spin-orbit coupling in the asymmetric quantum well.
