Abstract

Semiconductor "sinusoidal superlattices" of ZnSexTe1-x - that is, periodic structures in which the chemical composition parametrized by x varies sinusoidally along one direction - were fabricated by rotating a substrate through an inhomogeneous distribution of constituent fluxes within a molecular beam epitaxy growth chamber. The modulation of chemical composition x is accompanied by modulation of strain, owing to the difference in Zn-Se and Zn-Te bond lengths. By fitting x-ray diffraction scans around the (002), (004), and (006) Bragg reflections for (001)-oriented ZnSexTe1-x sinusoidal superlattices to a simple scattering theory, we have determined both the strain and the chemical modulation amplitudes in these structures.
