Infrared ellipsometry

Infrared spectroscopy (IRS) is a powerful analytical method with high detection and chemical sensitivity. It has been used in the characterisation of semiconductor interfaces for decades. A special advantage of IRS is its sensitivity not only for molcular vibrations, but also for excitations of free charge carriers. Hence, it offers the possibility to gain information on the electrical conductivity of a sample without the need for direct contacts.
