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 09. April 2021.

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 2021).

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

This lecture series is primarily intended for master students which have already attained good knowledge of solid-state physics. The lectures are complemented by a practical which focuses on the measurement of important transport parameters: electrical conductivity, Seebeck coefficient and thermal conductivity of thin film samples. The practical will be held at Helmholtz-Zentrum Berlin für Materialien und Energie with a written report being part of the requirements to successfully pass the course. Bachelor students are also admitted. However, basics of molecular physics and solid-state physics are expected as well as participation in the practical session.

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 ECTS points

Electronic Transport: 

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

Thermoelectric effects: 

• Seebeck effect, 
• Peltier effect.

Scattering Processes:

• ionized-impurity scattering,
