Condensed Matter Physics

This course deals with concepts required to study macroscopic and microscopic properties of matter. These theories include bonds in molecules, potential energy diagrams for molecules, crystal structure, electrical conductivity and free-electron fermi gas, molecular spectra and bonding in solids. It then goes on to explain band theory in solids, semiconductors, superconductivity and doping that change the electrical properties of solids. The course concludes by application of doping in semiconductor diodes, transistors, and integrated circuits.

Condensed Matter Physics - Intro

In physics, condensed matter physics is a branch of physics that deals with the macroscopic physical properties of matter. Condensed matter physicists seek to understand the behavior of these properties, which typically occur at extremely low temperatures and very high densities. The most familiar examples of condensed matter include solids and liquids, which can be contrasted with gases, the other states of matter. The distinction between the two is not sharply defined, but generally, liquids are "liquids" when they are able to flow, while solids are "solids" when their constituent particles are "locked in place".

Bonds - Overview

In chemistry, a bond is a lasting attraction between atoms that enables the formation of chemical compounds. A bond is usually considered to be the force that holds atoms together in a chemical compound. The bond may result from the electromagnetic force, the force of attraction between nuclei for atoms and molecules, or a combination of these forces. The bond strength is directly proportional to the atomic or molecular binding energy.

Band Theory - Overview

In physics, a band is a range of energy levels for electrons in a solid, usually referring to the conduction band and the valence band. The conductivity of an electrical insulator is determined by the amount of charge that it can transfer per unit time, which is proportional to the number of electrons in the conduction band. The valence band is the highest energy band of electrons within a solid, and its electrons are responsible for chemical bonding with other atoms.

Semiconductor Devices - Overview

A semiconductor diode is a two-terminal electronic component that conducts primarily in one direction. A semiconductor diode is constructed from a single p-n junction. This p-n junction has a very high resistance to the flow of electrons in the reverse direction. This property is called rectification, and the diode is used to convert alternating current (AC) to direct current (DC).

Superconductivity - Overview

Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic flux fields occurring in certain materials (superconductors) when cooled below a characteristic critical temperature. It was discovered by Heike Kamerlingh Onnes on April 8, 1911 in Leiden. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical phenomenon. It is characterized by the Meissner effect, the complete ejection of magnetic field lines from the interior of the superconductor as it transitions into the superconducting state.
