Abstract
Nondestructive room temperature photoluminescence of the InGaAs channe l of a pseudomorphic high electron mobility transistor is presented as a function of bias applied to a semitransparent gate. The channel ele ctron sheet concentration is evaluated via line-shape fitting of the p hotoluminescence spectrum. Excellent agreement with electrically deriv ed values of the channel charge was found. Information on the symmetry of the channel potential is also provided by the results of the photo luminescence line-shape fit.
