Map ESR Project 9

Objectives

  • Theoretical characterization of electronic and thermoelectric properties of organic polymeric materials by atomistic and ab initio simulations and multi-scale transport calculations
  • Guiding experiments to develop realistic strategy to enhance the conductivity and Seebeck coefficient in polymeric thermoelectric materials and providing input to phenomenological approaches (Monte Carlo and Drift-Diffusion)

Expected results

  • Calculation of the DOS of realistic organic polymeric thermoelectric taking into account effects of disorder, presence of counter ions, screening etc.
  • Dynamics of quasiparticles (polarons, bipolarons) in polymer chains and dynamics of interchain electron transfer.
  • Calculations of electronic part of thermal conductivity
  • Multi-scale models for electron transport without adjustable phenomenological parameters.

Skills acquired

  • Ab initio calculation of electronic structure and DOS of complex polymer materials
  • First-principle Molecular Dynamics methods
  • Tight-binding DFT
