文摘
- •
We have studied the effects of Rashba and Dresselhaus spin-orbit coupling on the polaron properties in wurtzite GaN quantum well.
- •
The electron-phonon interaction and polaron mass correction are both significantly enhanced by the spin-orbit coupling.
- •
For the interface optical phonon modes polaron self-energy takes the big values than for the confined optical phonon modes.
- •
The polaron effective mass exhibits anisotropy.
- •
The contribution of the Dresselhaus spin-orbit coupling term in the polaron effective mass is larger than Rashba one.
