Project title: Electrocrystallization of Organic Charge-Transfer Salts
Project description (50-100 words suggested): Many polycyclic aromatics can form crystalline charge-transfer salts with semiconducting, metallic or even superconducting properties. These materials are being actively investigated for their application in “organic electronics”, which make it possible to fabricate variety of electronic devices – light-emitting diodes (OLED), solar cells, transistors (OFET), switches, memories and sensors from purely organic matter. In these applications organic semiconductors have many advantages, such as ease of fabrication, mechanical flexibility, and low cost. In addition to the applications, organic conductors have a number of fascinating properties from the more fundamental scientific perspective; e.g. they typically exhibit a very rich phase diagram with metal-to-insulator structural phase transitions and stable charge-density wave phases.
The goal of this project is to grow crystals (primarily by electrochemical methods) of a variety of charge transfer salts and prepare them for characterization in a conventional transmission electron microscope and for time-resolved studies on the ultrafast electron diffraction instrument in the Siwick lab.
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): Final grade shall be based on laboratory performance as evaluated by the research supervisor (50%) and the final written research report (minimum 10 pages) graded by the supervisor and the course coordinator or the coordinator's delegate (50%)
