摘要

We have performed a magnetotransport study in both perpendicular and parallel magnetic fields for gated InAs/GaSb double heterostructures. These measurements provide a further proof for the existence of a minigap at the anti-crossing point between the electron and hole dispersion relations in this system. When a parallel magnetic field is increased from 0 to 12 T, the resistivity drops by 60% when the Fermi energy is in the middle of the minigap, but by less ;than 3% when the Fermi energy is positioned outside the minigap.
