Far-infrared studies of extremely high mobility gated GaAs/AlGaAs structures in magnetic fields

Journal Article


Abstract

  • Extremely narrow cyclotron resonance linewidths are reported in GaAs-based heterostructures measured using double-modulated far-infrared photoconductivity. At low carrier densities and temperatures full widths at half maximum as small as 6 mT are observed.
