Abstract

Infrared absorption spectroscopy, in transmission and reflectance modes, Raman light scattering spectroscopy and X-ray rocking curve imaging analytics have been applied to characterize optical and structural properties of n-type and p-type bulk germanium crystals doped above the Mott transitions. Such materials are considered for mid-infrared technology complementary to silicon-based devices.
