| Abstract | We report experimental results of quantum transport through InAs/AlSb/GaSb/AlSb/InAs heterostructures having well widths of 7.0, 8.0, and 11.9 nm, respectively, in magnetic fields of up to 8.0 T aligned parallel to the epitaxial growth planes. Application of this resonant magnetotunneling spectroscopy technique allows the well subband dispersions to be probed along the wave vector perpendicular to both the growth direction and the applied magnetic field. In all three samples we observe little change in the current-voltage characteristics below a sample-dependent critical magnetic field B_(crit). Above this critical field, both the main I-V peak and a subsequent shoulder that forms at high fields shift in bias in a manner we attribute to be related to the HH2 and LH1 subbands (where HH and LH denote heavy and light holes), respectively. |
