Solid State Physics

Solid State Physics. Instructor: Prof. Amal Kumar Das, Department of Physics, IIT Kharagpur. This course will discuss the structure of solid materials and their different physical properties along with underlying physics. Firstly, this course will discuss about atom and from atom to how solid state structures are formed. Then it will discuss crystal symmetry, unit cells and crystal planes, real space and reciprocal space of crystal. It will discuss how crystal structures are determined experimentally using the X-ray diffraction. After that the course will discuss different properties of solids such as this thermal properties of solids, electrical properties of solids, magnetic properties of solids, and dielectric properties of solids.
