Fourier transformed IR and thermogravimetry analyses revealed that heating of the polymer precursor to 300 degrees C led to the cross-linking and partially to germanium separation in the cast films. Triple C C bonds transform into sp(3) carbon structure and Ge-C bonds break to form new Ge-H ones. Increasing of temperature to 700 and 1100 °C resulted in dehydrogenation and gradually germanium evaporation from films as showed by EDX. As a result, at 1100 °C Si/C films were prepared with embedded regions of germanium.
