Title: A High-Throughput Thermoelectric Power-Factor Screening Tool for Rapid Construction of Thermoelectric Property Diagrams
Published: January 23, 2007
Abstract: We have developed a high throughput screening tool that maps out thermoelectric power factors of combinatorial composition-spread film libraries. The screening tool allows us to measure the electrical conductivity and Seebeck coefficient of over 1000 sample points within 6 hours. Seebeck coefficients of standard films measured with the screening tool are in good agreement with those measured by traditional thermoelectric measurement apparatus. The rapid construction of thermoelectric property diagrams is illustrated for two systems: (Zn,Al)-O binary composition-spread film on Al2O3 (0001), and (Ca, Sr, La)3Co4O9 ternary composition-spread film on Si (100).
