EP364 SOLID STATE PHYSICS INTRODUCTION Aim of Solid State Physics Solid state physics (SSP) explains the properties of solid materials as found on earth. The properties are expected to follow from Schrödinger’s eqn. for a collection of atomic nuclei and electrons interacting with electrostatic forces. The fundamental laws governing the behaviour of solids are known and well tested.

EP364 SOLID STATE PHYSICS INTRODUCTION Crystalline Solids We will deal with crystalline solids, that is solids with an atomic structure based on a regular repeated pattern. Many important solids are crystalline. More progress has been made in understanding the behaviour of crystalline solids than that of non- crystalline materials since the calculation are easier in crystalline materials.

EP364 SOLID STATE PHYSICS INTRODUCTION What is solid state physics? Solid state physics, also known as condensed matter physics , is the study of the behaviour of atoms when they are placed in close proximity to one another. In fact, condensed matter physics is a much better name, since many of the concepts relevant to solids are also applied to liquids, for example.

EP364 SOLID STATE PHYSICS INTRODUCTION What is the point? Understanding the electrical properties of solids is right at the heart of modern society and technology . The entire computer and electronics industry relies on tuning of a special class of material, the semiconductor , which lies right at the metal- insulator boundary . Solid state physics provide a background to understand what goes on in semiconductors.

EP364 SOLID STATE PHYSICS INTRODUCTION Solid state physics (SSP)  is the applied physics New technology for the future will inevitably involve developing and understanding new classes of materials . By the end of this course we will see why this is a non-trivial task. So, SSP is the applied physics associated with technology rather than interesting fundamentals.

EP364 SOLID STATE PHYSICS INTRODUCTION Electrical resistivity of three states  of solid matter How can this be? After all, they each contain a system of atoms and especially electrons of similar density. And the plot thickens: graphite is a metal , diamond is an insulator and buckminster-fullerene is a superconductor . They are all just carbon!

Among our aims - understand why one is a metal and one an insulator , and then the physical origin of the marked features. Also think about thermal properties etc. etc.
