Calendar Description

The structural, mechanical, and electronic properties of matter will be discussed. Topics will include methods to fabricate nanostructured materials such as nanoparticles, nanocomposites, thin films, polymers and ferrofluids, as well as techniques that have been developed to analyze these materials, including scattering, microscopy and spectroscopy.

Prerequisites

NANO*2000 (Synthesis and Characterization of Nanomaterials I).

Objectives

This course first introduces periodical structures of crystalline solids, in both direct and reciprocal lattice descriptions, and the characterization of such lattices by diffraction methods. Then some basic concepts and methods of quantum mechanics will be introduced for describing the electronic structure of crystalline solids, i.e. the energy band structures as well as the effect of quantum confinements of nanoscale systems. The third aspect of the course involves mechanisms of characterizing nanomaterials by optical methods, some concepts of electrodynamics will be introduced and the system size dependent resonance conditions described.

Course Policies

Consideration for Illness, etc.

If you request academic consideration due to illness of a physical, psychological or emotional nature, or due to compassionate reasons, you may be required to provide suitable documentation (e.g., a medical certificate from a physician) at the discretion of the lecturer. See the Undergraduate Calendar for details.

Getting Help

Office Hours: Tuesday 1:00 pm – 4:00 pm; or by appointment.
Additional office hours can be arranged during the time approaching exams, and these hours will be announced in class or via the course-link site.

Collaboration versus Copying

Students are encouraged to discuss with each other during working on the problem assignments. However, the work that you submit as your assignment must not be a copy of someone else's work. Identical scripts will be given a mark of zero and plagiarism will be dealt with severely. Proper citations should be provided when books and other articles are used in your works.

Course Assessment

The Department of Physics requires student assessment of all courses taught by the Department. These assessments provide essential feedback to faculty on their teaching by identifying both strength and possible areas of improvement. In addition, annual student assessment of teaching provides part of the information used by the Department Tenure and Promotion Committee in evaluating the faculty member’s contribution in the area of teaching. The Department’s teaching evaluation questionnaire invites student response both through numerically quantifiable data, and written student comments. In conformity with University of Guelph Faculty Policy, the Department Tenure and Promotion Committee only considers comments signed by students (choosing “I agree” in question 14). Your instructor will see all signed and unsigned comments after final grades are submitted. Written student comments may also be used in support of a nomination for internal and external teaching awards.
