| Abstract: | The magnetic field dependence of cyclotron resonance linewidth (CRLW) due to electron-acoustic phonon interactions in the extreme quantum limit is obtained on the basis of Kubo's formula and Fujita's diagram method. The 2-dimensional electron-piezoelectric phonon interaction generates a finite maximum CRLW as a function of magnetic field while CRLW for all other acoustic polarons increase with the magnetic field. |
