COURSE OBJECTIVES:

  • To identify and describe the types of bonding found in materials
  • To develop the language to describe crystal structures and their symmetries
  • To identify and describe the different types of defects that are found in real crystal structures

DESIRED COURSE OUTCOMES:

  • Understanding the definition of a lattice and a crystal.
     
  • Identification of crystalline symmetries including translational and point symmetries.
     
  • Familiarity with and the ability to read and interpret the International Tables of Crystallography, 230 Space groups.
     
  • Understanding stereographic projections; stereograms of the 32 crystallographic point groups.
     
  • Understanding the relationship of symmetry to physical properties.
     
  • Understanding of the reciprocal lattice and its relationship to diffraction experiments.
     
  • Understanding the quantum mechanical origins of bonding; Schrodinger’s equation, the particle in the box, solution to the hydrogen atom, and the band theory of solids.
     
  • The ability to identify the characteristics of metallic, covalent, ionic and van der Waal’s bonding.
     
  • The ability to identify and describe the different types of defects found in crystals: dislocations and point defects.
     
  • Understanding the importance of defects for materials properties.

TOPICS COVERED:

Crystal structures; points, directions and planes; unit cell; Bravais lattice; basis; symmetry- translation, rotation, inversion; 32 Crystallographic Point Groups; 230 Space Groups; real and reciprocal Lattices; Brillouin zones; application of reciprocal lattices to diffraction- scattering from electrons, atoms, crystals; structure factor; van der Waal’s, ionic, covalent and metallic bonding; classical versus quantum mechanical picture of bonding; particle-wave duality, Schrodinger’s equation; particle-in-a-box, metallic solid; hydrogen atom, covalent solid; band theory of solids; importance of defects on properties; point and line defects.

COURSE FORMAT:

Three hours of lecture and one hour of discussion per week.

CONTRIBUTION OF THE COURSE TO MEETING THE PROFESSIONAL COMPONENT:

This course will provide the foundation for understanding the relationships among the structure and properties of materials that may be incorporated into a range of applications.

RELATIONSHIP OF THE COURSE TO UNDERGRADUATE DEGREE PROGRAM OBJECTIVES:

MSE 102 is the first of the core courses for the MSE single and double majors. It provides the foundation for understanding bonding, crystallography and crystal defects, especially in crystalline materials.

ASSESSMENT OF STUDENT PROGRESS TOWARD COURSE OBJECTIVES:

  • 8 problem sets: 25%
  • two in-class exams: 20% each
  • final exam: 35%
