The course focuses on understanding the basic principles and laws of objects from nanoworld. Classical thermodynamic approach is extended to the basic principles of quantum-mechanical description of nano-objects. Particular attention is paid to the methodologies estimating the equilibrium shape of nanoparticles, depending on the number of atoms forming individual particle. An important part of the course is a list of suitable preparation and characterization techniques for nano-objects of different dimensions (quantum dots, nanowires, nanolayers).
Aim of the course
