Abstract
⺠Crystallographic properties of Ba8GaxSi46âx clathrates are characterized. ⺠Arc melting and spark plasma sintering process enables increase of Ga content. ⺠We elucidate the Ga composition dependence of thermoelectric properties. ⺠Thermoelectric figure of merit ZT is improved due to the increased Ga content. ⺠Calculation predicts a potential ZT=0.8 at 900 K at optimized carrier concentration.
