The large angle convergent beam electron diffraction technique has been used to obtain rocking curves from MOVPE and MBE grown InP-In.53Ga.47As single quantum well samples. Reflections sensitive to strain within the well layer were studied. From analysis of the curves an estimate of the mean strain present within the well in the samples has been made. Strains as low as 1.2.10(-3) have been measured. Plan-view specimens were used, reducing the problem of surface relaxation effects often encountered in thin cross-sectioned foils.
