Abstract :
This study presents the growth of strain-symmetric Si/SiGe THz quantum cascade structures on virtual substrates with precise layer parameters, thick active region, and high material quality. Sample characterization is done using atomic force microscopy, high resolution X-ray diffraction, and transmission electron microscopy.
