Notes:
The composition of Alx Ga1−xAs has been measured with improved accuracy by electron probe microanalysis using an aluminum-copper alloy standard rather than an elemental aluminum standard. Details of the experimental procedure are given. A calibration curve, relating the photoluminescence peak energy (Ep) to aluminum concentration (x), has been obtained. A least-squares fit to the data gives Ep(eV)=1.42+1.45x−0.25x2 for 0〈x≤0.45.
