  5. κ = Thermal conductivity (W m -1 K -1 ) σ = Electrical conductivity ZT ≥ 2 needed for ( Ω cm -2 ) competitiveness α = Seebeck coefficient (1) ( V K -1 ) Figure of merit: Sébastien Moitzheim, IA-Tokyo, 2012 5

  6. Electrical conductivity ↑ Thermal conductivity ↑ ZT ↓ (1) Sébastien Moitzheim, IA-Tokyo, 2012 6

  7. Each material has its own optimal working temperature  Choosing the right material for the right application Important factors:  Cost  Efficiency (2)  Stability Sébastien Moitzheim, IA-Tokyo, 2012 7

  9. Bulk nano-Si  Bulk nano-silicon  JST- CREST: “ Development of High Efficient Silicon Thermoelectric Materials using Si-nanodeeltjes Nanostructure Control ” 2012 -2017 (¥150M) Ladingstransport  Osaka University Warmte wordt geblokkeerd  AIST Oxide nanocubes  e.g. Strontium Titanate (SrTiO 3 ) JST Project: “ Development of High-Efficiency  Thermoelectric Materials and Systems” FY 2007 -2013 (¥227M) Nagoya University  Hokkaido University  Tokyo University of Science, Yamaguchi  AIST  Sébastien Moitzheim, IA-Tokyo, 2012 9

  10. 1. Use ball-milling to get silicon (Si) particles 2. Oxidize Si particles 3. Etch away SiO 2 4. Use spark plasma sintering (SPS) to form bulk nano-silicon Goal: ZT >1 between RT and 300 °C Sébastien Moitzheim, IA-Tokyo, 2012 10

  11.  Recently used to create the best (bulk) thermoelectric material in USA, Nature 2012/09 (ZT = 2.4)  However materials used (Lead Tellurium) are toxic  Japan wants to use life-friendly and abundant materials  World leader in Spark Plasma Sintering (SPS) equipment is Fuji Electronic Industrial (3) Sébastien Moitzheim, IA-Tokyo, 2012 11

  12.  Large variety of raw materials can be used  Fast process  New types of (nanostructured) materials Sébastien Moitzheim, IA-Tokyo, 2012 12

  13. Sébastien Moitzheim, IA-Tokyo, 2012 13

  14.  Strontium Titanate (STO) nanocubes  Dope with a thin shell of Niobium  And a core of Lanthanum  2D electron gas:  Many interfaces: high electrical conductivity Low thermal conductivity Sébastien Moitzheim, IA-Tokyo, 2012 14
