Introduction to Solid State Physics

Indian Institute of Technology Kanpur and NPTEL via Swayam

Overview

The course deals with introducing concepts of condensed matter physics to advanced undergraduate and postgraduate students. The course will be pitched at the level of a first year course in MSc in Physics. For this course, an exposure to undergraduate level of: (a) quantum mechanics, (b) statistical and thermal physics and (c) electromagnetic theory, is expected for this course. It is hoped that through this course, the student will understand the quantum theory of solids which is used to describe the thermal and electrical properties of a solid. The student will explore the interaction of a solid with electromagnetic radiation like X-rays and how this can be used to understand the atomic crystal structure of the solid. During the course the student will be exposed to some experiments related to probing various properties of solid INTENDED AUDIENCE : Any Interested Learners PREREQUISITES : Students who have familiar with basic knowledge in quantum mechanics, statistical mechanics, thermodynamics, electromagnetism and classical mechanics
