Abstract

Far-infrared (FIR) photoconductance studies on HgTe/CdTe superlattice (thickness 110/220 Å.) show an absorption line near 16 cm^-1 associated with a resonant acceptor state. Quantum oscillations in ρ{variant}_xx and ρ{variant}_xy are consistent with an electron density n_s of 6 × 10¹¹ cm^-2. Combining the ρ{variant}_xx data with the FIR data we deduce a Fermi energy of 45 mev. A temperature dependent high-field anomaly in ρ{variant}_xx near 20 T suggestive of a new electronic phase is also observed.
