Band Structure Near the Dirac Point in HgTe Quantum Wells with Critical Thickness

Band Structure Near the Dirac Point in HgTe Quantum Wells with Critical Thickness

Mercury telluride (HgTe) thin films with a critical thickness of 6.5 nm are predicted to possess a gapless Dirac-like band structure. We report a comprehensive study on gated and optically doped samples by magnetooptical spectroscopy in the THz range. The quasi-classical analysis of the cyclotron re...
