Magnetoplasma effects in semiconducting Bi1–xSbx alloys

Abstract: The magnetic-field-dependent microwave absorption is measured in semiconducting Bil -,Sb, alloys in the frequency ranges of 36 and 70 GHz a t helium temperatures. I n addition to cyclotron resonance, tilted orbit resonance ist observed. A theoretical lineshape analysis is carried out. The comparison with the experiment shows good agreement. Moreover the hybrid resonance and the dielectric anomaly are discussed and their influence on the magnetic-field-dependent microwave absorption in the present material is i… Show more

“…As compared with 36.2 GHz, a t 131 GHz the resonances show a smaller relative half-width as well as a marked lineshape, which indicate the occurrence of Fabry-Perot resonances (cf. (12)). The decrease of the relative half-width with increasing w indicates t'hat the at'tenuation of the waves is a function of w t (T relaxation time).…”

“…I n weak magnetic field, a t 36.2 GHz one distinctly observes tilted-orbit resonance (cf. [12]). At 36 GHz the spatial resonances, except for those in the highest magnetic fields, satisfy the dispersion relation for low magnetic fields, ~, ' .…”

“…This paper shows that in addition to the resonances in the quasi-classical magnetic field (cf. [2]) further hybrid resonances may occur, if the charge carriers in the quantizing magnetic field are redistributed between different parts of the Fermi surface. This phenomenon is most suitable for obtaining information about the energy dependence of the dispersion relation of the charge carriers.…”
