Low thermal conductivity and improved thermoelectric performance of nanocrystalline silicon germanium films by sputtering

Si x Ge 1? x alloys are well-known thermoelectric materials with a high figure of merit at high temperatures. In this work, metal-induced crystallization (MIC) has been used to grow Si 0.8 Ge 0.2 films that present improved thermoelectric performance (zT= 5.6× 10? 4 at room temperature)—according t...
