Map ESR Project 12


  • Alignment of n- and p-type polymer semiconductors and controlled doping thereof
  • Influence of doping method on structure and TE properties
  • Influence of dopant chemical nature on structure of doped layers
  • Adapt oriented films to prepare TE devices using the coat-rubbing-fold method

Expected results

  • Enhance TE efficiency (conductivity and possibly Seebeck coefficient) through alignment
  • Understanding of dopant intercalation mechanism
  • Establish correlations between structure and TE properties in anisotropic thin films

Skills acquired

  • Preparation of highly aligned conducting polymer layers
  • Expertise in transmission electron microscopy and structural analysis of polymeric systems (low dose TEM)
  • Polarized UV-vis-NIR spectroscopy and TE measurements (conductivity and Seebeck coefficient) in anisotropic systems
