Nondestructive room temperature photoluminescence of the InGaAs channel of a pseudomorphic high electron mobility transistor is presented as a function of bias applied to a semitransparent gate. The channel electron sheet concentration is evaluated via line-shape fitting of the photolumin- escence spectrum. Excellent agreement with electrically derived values of the channel charge was found. Information on the symmetry of the channel potential is also provided by the results of the photoluminescence line-shape fit.
