goals

Nanoscale patterns with dimensions typical < 300 nm are characterized by unique properties and are widely discussed regarding to possible applications. The students become familar with these properties and learn to evaluate their use in microsystems and to specify and apply fundamental effects. Here, both well-established classical semiconductors like Si or GaAs/AlGaAs and new semiconductor materials like transition metal dichalcogenides are addressed.

Besides the descrition of the properties also techniques for preparation and characterization of nanostructures are presented allowing the students to decide whether and in what manner it is possible to integrate nanostructures.

content

From 3D nanostructures to 0D strucures:

  • Basics of nanoscale systems, short-channel effects
  • Characterization methods of nanoscale systems
  • Heterostrucures, quantum Hall effect
  • Conductance quantization, inertial ballistics
  • Carbon nanotubes, nanoribbons
  • Single electron effects, SET, Coulomb blockade
