Cyclotron-resonance line-width due to electron-LO-phonon interaction in cylindrical quantum wires

► Graphical dependence of absorption power on photon energy is obtained. ► Cyclotron-resonance line-width (CRLW) as profiles of the curves is determined. ► CRLW increases almost linearly as the temperature increases. ► CRLW increases strongly as the magnetic field increases with high magnetic fields. ► CRLW decreases strongly as the wire's radius increases with small wire's radius.
