• Analytic expressions for tlae absorption coefficient of a weak Blectronuagnetic Wave (BIVIW) byfree carriers for tlae case of electron-optical plaonon scatterirag in qttantttm welts are calculatedby the Ktrbo-lVIori rnethod in two cases: -The absence of' a taaagnetic field. -Tlue presence ofa naagnetic field applied perpendicular to its barriers. A dif['eretat dependence of the absorptionacoefficient on the teunperattrre T of systetta, tlae electrouaaagnetic xvave f'reqtrency w, the cyclotror'ufreqxzer'xcy Q (when a tnagnetic field is preserat), and chatracteristic pararaaeters of a qttantttrau wellin cornparison xvith norrnal serniconductors is obt?xiraed. The analytic exjcressions are ntrmericallyevaluated, plotted and discussed for a specific quanttmrau well AIAs/GaAs/AIAs.
