Silicides are an integral part of several important technologies, but current knowledge of their properties is fragmented and incomplete. Many phases still need to be explored and there is an urgent need for systematic determination and understanding of their transport properties.We will introduce a novel method to measure the thermal conductivity of sputtered material libraries and, in the most thorough investigation of phase stability, thermal and electric transport properties to date, a comprehensive, systematic and combined experimental and theoretical dataset will be produced. Data-mining techniques will be employed to find the underlying correlations between stability and thermal transport properties of complex phases. Furthermore, multi-phase silicides with tailored transport properties will be designed, thereby demonstrating an integrated combinatorial control of electrical and thermal transport properties in silicides.
