'Photothermal AFM' - PHYS 396 Undergraduate Research Project Application Form
INSTRUCTIONS - PROFESSORS: Please print and review this form. Complete or correct the sections, as applicable, from "Supervisor's Name" to "Ethics, safety, and training". Please sign and date near the bottom ("Supervisor's signature").
INSTRUCTIONS - STUDENTS: You may receive this form by email, or you may download it after it has been posted here. Either way, print and review this form. Complete or correct the sections, from "Student's Name" to "Student's Level", and sign ("Student signature"). Ask your supervisor to sign her/his section near the bottom. Take it to the department* corresponding to the course number in Section A; this may or may not be your own department. (* EXCEPTIONS: For NSCI 396 and COGS 396, please bring it to the Interdisciplinary Programs Adviser in Dawson Hall.) Do not register for a '396' course on Minerva until you receive departmental permission. Have a discussion with your supervisor about time/work expectations, keeping in mind that this is a 3-credit course (roughly, 10 hours per week for 12 weeks). Remember that a '396' course is an elective.
INSTRUCTIONS - DEPARTMENTS: After the unit chair/director/designate approves (or not) this project, please notify student. If approved, please give student permission to register on Minerva, and send a copy of this form (with signatures) to the Office for Undergraduate Research in Science (either fax, or internal mail to Dawson Hall 408-A, or PDF scan + email).

Project title: Photothermal AFM
Project description (50-100 words suggested): Generally, in non-contact atomic force microscopy (nc-AFM) the force sensing microfabricated cantilever needs to be oscillated with an amplitude of a few nm. Mechanical changes related to a force interaction manifest themselves as a change in oscillation amplitude and frequency. The cantilever is most often oscillated by a piezo electric element. This however also can lead to detrimental mechanical vibrations of the AFM system. A possible solution is to photothermally excite the cantilever. The project involves the implementation of photothermal excitation in AFM by coupling the IR excitation to a fiber optical interferometer used to sensitively detect the deflection of the AFM cantilever.
Prerequisite: 1 term completed at McGill + CGPA of 3.0 or higher; or permission of instructor.
Grading scheme (The final report must be worth at least 50% of final grade): 60% final report, 20% lab performance and 20% oral presentation.
Project status: This project is taken. The professor has no more '396' projects this term.
Ethics, safety, and training: Supervisors are responsible for the ethics and safety compliance of undergraduate students. This project involves NEITHER animal subjects, nor human subjects, nor biohazardous substances, nor radioactive materials, nor handling chemicals, nor using lasers.
