Theoretical and experimental aspects of molecular electronics

Jun.-Prof. Fabian Pauly & Prof. Elke Scheer

This lecture addresses students of Physics, Chemistry, or Molecular Materials Sciences and provides a compact introduction to the rapidly developing field of molecular electronics. It gives an overview on our present understanding of the electrical conduction in single-molecule circuits and a thorough introduction to the experimental techniques and theoretical concepts in an integrated manner. Students may deepen theoretical or experimental aspects by the choice of the exercises. The experimental focus includes a laboratory course that will partially be held at Research Center Dresden Rossendorf, see separate item. The theoretical one involves the solution of exercise sheets and programming tasks.
