Cyclotron resonance in quasi-two-dimensional conductors

A theoretical analysis is made of the resonant absorption of RF electromagn etic wave energy in layered conductors having a quasi-two-dimensional elect ron energy spectrum. An analysis is made of the influence of possible drift of carriers into the conductor and their Fermi-liquid interaction on the p osition of the cyclotron resonance lines. A reason is given for the substan tial difference between the cyclotron effective masses determined from the temperature dependence of the amplitude of the Shubnikov-de Haas oscillatio ns and from measurements of the cyclotron resonance frequencies in [5-7]. I t is shown that by means of an experimental investigation of cyclotron reso nance in a magnetic field parallel to the layers, it is possible to find th e carrier velocity distribution at the Fermi surface in layered organic con ductors.
