Abstract

V originále

In order to better understand the effects of the hydrogen incorporation on the defects and the disorder in the un-doped nano/microcrystalline SiGe:H, we performed a comparative study on samples deposited under different plasma conditions. With variation of the pressure, we were able to change the structure of SiGe:H films. We have used the combination of the infrared spectroscopy, CPM, PDS and thermal desorption measurements to study the thermal dependence of defect density, disorder, as well as hydrogen concentration. The film mechanical properties were test by depth sensing indentation technique. The results showing a different hydrogen bonding with the change of deposition conditions are interpreted as a whole by terms of the specific local hydrogen bond-ing environment, related to different growth mechanism.

In Czech

Pro lepší pochopení role vodíku na poruchy a uspořádanost nedopovaných nano a mikrokrystalických vrstev SiGe:H jsme zkoumali závislost mechanických a optoelektrických vlastností na depozičních podmínkách, zejména tlaku v plasmatu. \výsledky ukazují na různé chování vodíku v závislosti na růstovém mechanismu tenkých vrstev.
