Notes:
Magnetotunneling of holes through the double-barrier AlAs/In0.10Ga0.90As strained-layer structure is investigated with magnetic fields up to 23 T to determine the in-plane dispersion of the two-dimensional subbands in the In0.10Ga0.90As quantum well. Mass reversal, nonparabolicity, anticrossing, and anisotropy are observed. The lack of electronlike dispersion in the lowest-energy light-hole subband is attributed to the large biaxial compressional strain in the In0.10Ga0.90As, which suppresses the mixing of heavy and light-hole states even at finite in-plane wave vectors.
