Comparative energy levels analysis of Type I and Type II silicon clathrate films

Charif Tamin

Résumé

The two primary forms of silicon clathrates are Type I (Na8Si46) and Type II (NaxSi136). Both forms have been investigated for diverse silicon-based optoelectronic applications owing to their unique characteristics and cage-like structure. Determining the energy levels of these clathrates is crucial for device manufacturing, particularly because Type I clathrates display metallic characteristics and Type II clathrates are either semiconductors or metal depending on sodium “x” content. In this study, we established the energy levels of both Type I and Type II silicon clathrates. This offers crucial information for customizing these materials to meet specific optoelectronic device application requirements. Keywords:
