PHY1023 : Introductory Electromagnetism and Materials

Semester 2 Credit Value: 20
ECTS Credits: 10.0


To give an understanding of electromagnetic fields, the resultant forces, the origins of electricity and magnetism, and the theorems required to evaluate field properties symbolically and quantitatively.
To present the various forms semiconductor materials, their behaviour under in an electric field, and their use in devices;
To introduce concepts of states of matter with a focus on solid state materials to act as a foundation for later course;

Outline Of Syllabus

Origin of charge and forces between charges:- electric field, potential energy, capacitance, dielectrics, electric flux, dispersion and circulation;
Coulomb’s a and Gauss’ laws;
Magnetic Fields
The concept of a magnetic field, dispersion and circulation, circuit laws, flow concepts, flux, inductance, flux density, mmf, mmf gradient.
Ampere’s, Biot-Savart, Faraday’s and Gauss’ laws for magnetism.
Magnetic materials including ferromagnetism and hysteresis
forces of attraction and alignment; force on current carrying conductors.
Metals, semiconductors, and devices:
Charge within a solid(multiatom):- energy bands and their occupation, forbidden energy gap, difference between metals, semiconductors and insulators
Changing the distribution of charge in the energy bands:- effect of temperature, electrons and holes, doping as a means of increasing the electrons and holes in a semiconductor
Current flow due to an electric field in metals and semiconductors:- electric field currents, resistivity, conductivity
Current flow due to diffusion in non-uniform doped semiconductors:- diffusion currents, built-in electric field
PN junctions:- barrier height, depletion layer and current flow under zero bias, forward bias and reverse bias; explanation of the diode equation, diode capacitance
Light emitting diodes and photodiodes
States of matter:
Bonds between atoms: ionic bonds, metallic bonds, covalent bonds, molecular bonds, comparative strength of the bonds.
Ideal Gases: kinetic theory, specific heat of gases, mean free path.
Gas-liquid phase transitions: modifications to the ideal gas equation, continuous and discontinuous transitions between liquids and gases.
Liquids: the role of intermolecular forces in understanding surface tension and viscosity.
Order-disorder transitions: amorphous solids, liquid crystals.
Solids: the unit cell, crystal planes, methods of determining crystal structures.

Assessment Rationale And Relationship

The examination provides the opportunity for the student to demonstrate their understanding of the course material. The problem solving aspects of the assessment enable students to demonstrate that they are able to apply this understanding and their analysis and synthesis skills to novel situations.
