Course Content (Syllabus)
Mechanical Properties and strength of materials: 1. The concepts of stress and strain. Hooke’s law. Young, shear, and bulk moduli, Poisson ratio, strain energy, thermal strain. 2. The stress tensor. Normal and shear strain on an inclined plane. Plane stress state. Principal stresses in three dimensions. Analysis of the stress tensor. Graphical determination of the normal and shear stresses as a function of principal stresses using the Mohr approach. Inhomogeneous stress – Diffrential equations of equilibrium. 3. Description of the strain state at a point. Plane strain state. Compatibility of strains. 4. Stress-strain relationand elastic energy in the 3D case. Anisotropic elasticity. The generalized Ηοοke’s law. Generalized plane stress and strain states. Torsion. Case studies. 5. Plastic deformation of materials. Plastic flow criteria. Ductile and brittle fracture. Griffith criterion. Creep. Hardness. 6. Experimental determination of mechanical properties (tension, bending, fracture toughness, creep, hardness).Evaluation : Final exam
Electrical Properties: Electrical conductivity in metals, alloys, semiconductors and semiconductor devices. Superconductivity and superconductor devices. Dielectrics. Evaluation : Final exam
Magnetic properties of materials for technological and biomedical applications: Brief description of the basic magnetic sizes and units as well as of the basic kinds of magnetic order. Description of materials according to their magnetic properties and the desired applications (hard magnetic materials, permanent magnet materials, amorphous, nanocrystalline, soft magnetic materials, magnetic nanoparticles, giant magnetoresistance, giant magnetostriction, magnetic recording, magneto-optical materials). Emphasis is given on the relation between the intrinsic properties and the extrinsic properties that the materials acquire after proper treatment, which lead to specific characteristics for the designed technological and biomedical applications. Evaluation : Final exam. Optionally, the students can take a term paper that will amount to 20% of the final grade.
Optical Properties and spectroscopy: General description of the optical properties of materials (semiconductors, metals, glasses) and optical coefficients. Light interaction with matter (Maxwell’s electromagnetic theory and semiclassical approach). Light absorption from materials (fundamental, excitonic, free carrier, lattice and defect related absorption). Light reflectivity from metals and semiconductors. Electro- and photoluminescence from semiconductors. Luminescence centers.
