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 ns 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.
