Density-chopped far-infrared transmission spectroscopy to probe subband-Landau splittings and tune intersubband transitions

We study the half-field subband-Landau resonant splitting of a two-dimensional electron gas and demonstrate the possibility to tune the intersubband spacings via density-chopped far-infrared transmission spectroscopy in the absence of external magnetic field.
