Email: djiang@uoguelph.ca

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.

Evaluation

Assignment deadlines will be enforced with a late penalty of 10% per day. Once the tutorial session covering content of the assignment is commenced no submission will be accepted.

Midterm Examination

Date/Time TBA, Online limited time and open-books.

Final Examination

April 17th (Sat.), 2:30 pm to 4:30 pm, Online limited time and openbooks.

Lectures

M/W/F 12:30 pm - 1:20 pm

Online Zoom Meeting, to facilitate the in-class discussions (a form of participation) it is expected that all participants have their camera turned on. Meeting invitations will be post on the course-link site, and maybe will be sent to the class participants for the first few meetings to establish this routine.

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: Thursday 2:00 pm – 4:00 pm, I will initiate a zoom meeting and sent out invitation to everyone, you decide if you need to participate and if you prefer to discuss with me individually we could have that arranged by separate appointments but not during these office hours.

Additional office hours can be arranged during the time approaching exams, and these hours will be announced in class or via the CourseLink site. Per request or the need of the class, will initiate discussion areas on the D2L site associated with specific assignments, quizzes, exams, to discuss in a forum fashion.

The University will not normally require verification of illness (doctor's notes) for fall 2020 or winter 2021 semester courses. However, requests for Academic Consideration may still require medical documentation as appropriate.

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.

By enrolling in a course, unless explicitly stated and brought forward to their instructor, it is assumed that students agree to the possibility of being recorded during lecture, seminar or other “live” course activities, whether delivery is in-class or online/remote.

If a student prefers not to be distinguishable during a recording, they may:

1. turn off their camera
2. mute their microphone
3. edit their name (e.g., initials only) upon entry to each session
4. use the chat function to pose questions.

Students who express to their instructor that they, or a reference to their name or person, do not wish to be recorded may discuss possible alternatives or accommodations with their instructor.

Online Behaviour

Inappropriate online behaviour will not be tolerated. Examples of inappropriate online behaviour include:

• Posting inflammatory messages about your instructor or fellow students
• Using obscene or offensive language online
• Copying or presenting someone else's work as your own
• Adapting information from the Internet without using proper citations or references
• Buying or selling term papers or assignments
• Posting or selling course materials to course notes websites
• Having someone else complete your quiz or completing a quiz for/with another student
• Stating false claims about lost quiz answers or other assignment submissions
• Threatening or harassing a student or instructor online
• Discriminating against fellow students, instructors and/or TAs
• Using the course website to promote profit-driven products or services
• Attempting to compromise the security or functionality of the learning management system
• Sharing your user name and password
• Recording lectures without the permission of the instructor

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.
