Course detail

Surface and Thin Films

FSI-T1T-AAcad. year: 2020/2021

This course is the introduction to series of courses engaged in study of physical problems of two dimensional structures surfaces, interfaces and thin films. Introduction of course is give up to problematic of clean surface: technology for preparation of surfaces and interfaces, its morphology and structure, brief description of two dimensional lattice vibration and electron structure of surface. Following part pay the attention to interaction between surface (interface) and surrounding medium and responsive changes of their physical properties: scattering of particles on solid state surface, kinetics and dynamics of elementary processes on surface (interface) adsorption, diffusion, desorption and sputtering. Last part talks about reactions on solid state surface (heterogenic catalysis), mechanics of thin film growth, properties and applications of thin films (except optical properties).

Learning outcomes of the course unit

Students will get knowledge on fundamental phenomena at solid surfaces during thin film growth and on principal analytical methods of surfaces and thin films.

Prerequisites

Atomic Physics, Solid State Physics, Quantum Physics, Statistical Physics and Thermodynamics, Vacuum Physics and Technology.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Practice consisting of panels and prepared individually by students under assistance of recommended literature are obligatory. At the examination the performance of students at practising will be taken into account, consultation of teaching materials and textbooks during writing a test is allowed. At the oral part of the exam discussions on problems of surface and interfaces physics will be carried out.

Aims

The aim of the module is to provide students with basic ideas of modern surface and interface physics in order to be capable of understanding microscopical nature of matter and principles, which the advanced materials technologies and modern experimental methods are based on.

Specification of controlled education, way of implementation and compensation for absences

The presence of students at the practice is monitored by a tutor. The way how to compensate missed practice lessons will be decided by a tutor.
