Abstract
Terahertz electroluminescence due to light hole-heavy hole intersubband transitions in p-type Si/SiGe quantum cascade structures has been observed in both surface-normal and edge emission geometries. THz output powers of up to 50 nW have been observed for surface emission from 100 period Si0.76Ge0.24/Si heterostructures grown on a Si0.8Ge0.2 relaxed buffer or 'virtual substrate'.
