Thin Film Science (NANO*3500)

Course Outline

This course introduces nanoscience students to concepts that are central to the study of thin films, surfaces and interfaces. Following an introduction to liquid and solid surfaces, fundamental forces acting at interfaces and basic surface thermodynamics are discussed. This leads to a discussion of different deposition techniques, characterization techniques and instabilities that are inherent to thin films. There is a laboratory component to the course that complements the material discussed in lectures and allows the students to become proficient on a broad range of surface-sensitive equipment.

Calendar Description

The deposition and growth of thin layers of materials is an important process on the production of many devices. This course will study the various methods by which thin films are grown including physical and chemical vapour deposition, molecular beam epitaxy, atomic layer epitaxy, and self-assembled monolayers. Experimental techniques for analyzing the properties of thin films will also be discussed.

Prerequisites: NANO*2100 Analysis of Nanomaterials

Instruction

John's research focuses on developing a fundamental understanding and predictive power for the physical properties of polymers, biopolymers and bacterial cells at surfaces and in thin films. He applies a broad range of surfacesensitive experimental techniques and fundamental, physics-based strategies to develop simple models of these complex soft matter systems.

Course Learning Objectives

This course will use a multidisciplinary approach to present new concepts and build on concepts covered in previous physics, chemistry and nanoscience courses.

The objectives of this course are:

1. 1) Introduce physical concepts and mathematical tools used to describe surfaces, interfaces and thin films
   • Develop an intuition for surface and thin film physical principles through plotting of functions using Maple
2. 2) Relate the mathematical results to practical applications and experiments
   • Develop an appreciation of the mathematical basis for experimental techniques for deposition and analysis of thin films
3. 3) Understand physical phenomena that can be exploited for the deposition of thin films
   • Demonstrate knowledge of different thin film deposition strategies
4. 4) Develop proficiency for experimental techniques used to deposit and characterize thin films
   • Demonstrate laboratory and data analysis skills
5. 5) Expand scientific writing skills to develop effective communication
   • Develop ability to analyze and synthesize implications of key results of published scientific studies

Evaluation

The assignments and the report on the research paper are due at the beginning of class on the due date. Unless there are exceptional circumstances, marks will be
deducted for lateness (10% per day). Marks will also be deducted for errors in English grammar and spelling in all work submitted for grading.

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. Details are provided in the undergraduate calendar:

Course Policies

HELP!

Short questions can often be handled in the lecture room just before or after lectures. Hours will be announced when John is almost certain to be in his office for consultation with students. He will make every effort to answer emails in a timely manner.

Academic Misconduct

The University of Guelph is committed to upholding the highest standards of academic integrity and it is the responsibility of all members of the University
community – faculty, staff, and students – to be aware of what constitutes academic misconduct and to do as much as possible to prevent academic offences from occurring. University of Guelph students have the responsibility of abiding by the University's policy on academic misconduct regardless of their location of study; faculty, staff and students have the responsibility of supporting an environment that discourages misconduct. Students need to remain aware that instructors have access to and the right to use electronic and other means of detection.

Please note: Whether or not a student intended to commit academic misconduct is not relevant for a finding of guilt. Hurried or careless submission of assignments does not excuse students from responsibility for verifying the academic integrity of their work before submitting it. Students who are in any doubt as to whether an action on their part could be construed as an academic offence should consult with a faculty member or faculty advisor.

The Academic Misconduct Policy is detailed in the Undergraduate Calendar: http://www.uoguelph.ca/registrar/calendars/undergraduate/current/c08/c08-amisconduct.shtml

Collaboration Versus Copying

Scientists often consult fellow scientists to discuss their research problems. Collaboration between scientists is often essential to perform world-class research. However, no ethical scientist would ever publish or claim the work of others as his or her own. Instead, joint publication or acknowledgements of the contributions of their collaborators is given.

The work that you submit for marking must be your own and not a copy of someone else's work. As a young scientist, you are encouraged to discuss with your fellow students as you learn the material and work on your assignments and presentations. However, plagiarism is a form of academic misconduct, and will not be tolerated. In your work that you submit for marking, you are encouraged to cite references and acknowledge discussions with others who have helped you to achieve an understanding of the material. This is good scientific practice.

Student 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 strengths 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 Promotions 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.

NOTE: No information will be passed on to the instructor until after the final grades have been submitted.

Note: John may be away several times during the semester to attend workshops and conferences, and to give research lectures. John will try to arrange that enthusiastic and talented replacement lecturers give lectures at the regular times. Otherwise, makeup lectures will be arranged at times that are agreeable to the students.
