Characterization of Ge-based clathrates oxidized in air by means of TEM and SEM

Germanium based clathrate-I compounds are considered for their potential applications due to possible thermoelectric and optoelectronic properties. Clathrate compounds may be an alternative to well known thermoelectric materials at higher temperature. In this contribution we examined the stability of these compounds annealed in air. Such experiments are important to simulate the compounds behavior under the conditions of a technological process, e.g. in a thermoelectric module.
