Near-Equilibrium Transport - Einzelansicht

If you are interested in the lecture please contact me by writing a short e-mail to habicht@helmholtz-berlin.de until 15. April 2020.

Details about the online lecture will be provided.

The series of lectures is complemented by a practical training at Helmholtz-Zentrum Berlin für Materialien und Energie,

Hahn-Meitner-Platz 1, 14109 Berlin, Campus LMC in Berlin-Wannsee.

The practical training includes the macroscopic characterisation of electronic transport (electrical conductivity, Seebeck coefficient) in a thin film sample,

duration: 1 day, date and time to be determined (at the end of or after SS 2020).

Proof of academic achievement: on the basis of a written report summarizing the experimental results of the parctical training.

Basic knowledge of solid state physics (electrons in single crystals, electronic dispersion, phonons) is required.

Proof of academic achievement: on the basis of a written report summarizing the experimental results of the practical training: 4.5 Leistungspunkte.

Electronic Transport: 

• Landauer-Datta transport model,
• Boltzmann transport equation.

Thermoelectric effects: 

• Seebeck effect, 
• Peltier effect.

Scattering Processes:

• ionized-impurity scattering,
• electron-phonon scattering (deformation-potential scattering),
• electron-electron scattering.

Thermal Transport:

• phonons in periodic crystals,
• thermal transport in the amorphous limit.

Experimental Methods:

• macroscopic measurement techniques for electric and thermal conductivity and Seebeck coefficients (van-der Pauw, 3 w method),
• microscopic techniques probing phonon lifetimes and electron-phonon coupling parameters.
