We present THz quantum cascade emitters realized on a Si substrate. The emission centered at 3.4 and 4.9 THz originates from L-valley transitions in strain-compensated n-Type Ge/SiGe heterostructures. This is an important step towards the realization of Si-based THz quantum cascade lasers.

Abstract
We present THz quantum cascade emitters realized on a Si substrate. The emission centered at 3.4 and 4.9 THz originates from L-valley transitions in strain-compensated n-Type Ge/SiGe heterostructures. This is an important step towards the realization of Si-based THz quantum cascade lasers.File in questo prodotto:
