Abstract

We report far-infrared (FIR) magnetoabsorption measurements on two Hg-based superlattices: HgTe/CdTe and Hg_0.90Mn_0.10 Te/HgTe grown by molecular-beam epitaxy. The latter one is novel and unique in that it is a superlattice of a zero-gap semiconductor and a narrow-gap diluted magnetic semiconductor. The FIR experiments were carried out at discrete photon energies between 2.5 and 12.8 meV in the temperature range 1.6 K < T < 200 K. Rich spectra of inter- and intraband transitions were observed, the intensities and positions of the transitions showing a dramatic temperature dependence associated with the thermal redistribution of electrons within the energy level scheme of the superlattices.
