Cyclotron Resonance of Free Magnetopolaron in Quantum Well Wires

Haiyang ZHOU Kadi ZHU Shiwei GU Dept.of Applied Physics , Jiaotong University , Shanghai , 200030 , China

材料科学技术（英文）

The cyclotron resonance of magnetopolaron in quantum well wires (QWWs) have been studied with the use of variational solutions to the effective mass equation. The results show that both the abso- lute value of the electron-phonon interaction energy and the cyclotron resonance frequency de- crease wi...
