Symposium P

Advanced Materials for Thermoelectrics

Thermoelectrics (TE) sits at the intersection of inorganic chemistry, solid state physicsa and nonequillibrium transport. Progress in TE has accelerated moving beyond nanotechnology and better understanding of band structures and phonon physics, moving towards ideal ‘phonon-glass-electron-crystal’-like materials. The TE community has especially been very active in applying new tools such as machine learning, high-throughput synthesis and characterization and materials screening to develop the field.

This symposium will cover recent progress in TE materials, including but not limited to bulk nanostructured materials, conducting polymers and inorganic-organic hybrids. Emphasis will be given on innovative design and synthesis routes of new materials, new physics concepts and unique thermoelectric module engineering principles. Submissions on development of measurement protocols for thin film Seebeck, thermal conductivity and powerfactor are encouraged. Theoretical ideas on not understanding fundamental properties, and predictive material design are welcome as they will synergize the search for next-generation TE materials.

1. Machine Learning, High Throughput Experiments and Process Optimization to synthesize bulk and nanostructured TE materials, accelerated analysis and testing.

2. Thermoelectric Materials Design, Synth;esis and preparation (conjugated polymers, inorganic-organic hybrids, nanocrystal arrays, quantum dots, nanowires, nanocomposites, 2D materials).

3. Thermoelectric Materials Characterization (Seebeck Coefficient, Thermal Conductivity – inplane and crossplane, Bulk thermoelectric coefficients, Thermoelectric Powerfactor, ZT).

4. Thermoelectric Concepts

  • Band Structure optimization in inorganic materials
  • Aligned conducting polymers and their properties
  • Structure-Property relations in thermoelectric materials
