Unit 1-1 Crystal Structure 

This video is a part of lecture series for NEP B.Sc. Vth Semester students having a physics course on "Solid State Physics". All the units prescribed in the curriculum prepared by Uttarakhand State Universities will be covered in this lecture series. It is the first lecture video of the series. This lecture describes some portions of crystallography, focusing on crystal structure, single and polycrystal, lattice and basis, primitive and non-primitive unit cell, seven types of crystal class, fourteen Bravais lattices and two-dimensional lattice structure.
