I am teaching
the following courses during the academic year 2009-10:
1. MT 209 "Crystal Defects" is now called
Defects in Materials-I (3:0) : This is one of the six soft-core
courses offered by the department. This will be offered in the Aug semester. We meet MWF
@ 10:00 A. The Materials Engineering Lecture Hall is being renovated, so we will
meet in one of the classrooms in the lecture hall complex.
Classes commence on 5th Aug, 2009, Wednesday.
Syllabus:
Review of basic crystallography and thermodynamics; Defect classification;
Defect equilibrium; Point defects in metallic, ionic and covalent crystals;
Dislocation theory - continuum and atomistic; Dislocations in different
crystals; Interface thermodynamics and structure; Overview of grain boundaries,
interphase boundaries, stacking faults and special boundaries; Volume defects;
Defects in non-crystalline materials; Defects and mechanical, electrical,
magnetic and optical properties; Defect characterization techniques.
Prerequisites: Knowledge of crystallography, characterization methods and
solution thermodynamics.

3. MT 304 Defects in Materials-II (2:1) : Also known as the Revenge of the Crystal Defects...This is an advanced level course and its being offered is subject to a minimum number of interested students. This will be offered once in two years - in the Jan semester of even years. The course will involve two hours of lecture each week and a tutorial class where we'll learn computational modeling techniques related to crystal defects. This will be offered again in January 2010
Syllabus:
Review of defects in materials; Point defects and diffusion; Electrical and
optical effects of point defects, Advanced dislocation theory; Dislocation
kinetics; Interface structure and energetics, Grain and special boundaries,
Interface kinetics: migration and sliding; Interfaces in phase transformation
and plastic deformation; Electronic properties of interfaces; Volume defects;
Defect interactions: point defect-dislocation interaction, dislocation-interface
interactions, segregation, high diffusivity paths, etc.; Atomistic simulation of
defects.
Prerequisites: Defects in Materials-I (MT209), Knowledge of crystallography,
structural characterization techniques and solution thermodynamics.
