ELECTROCHEMICAL NANOFABRICATION TECHNOLOGY

The Electrochemical Nanofabrication Technology course is designed for graduate level students who have research focus in the areas of nanofabrication, device design, low dimensional structures and engineering of nanomaterials. The main objective of this course is to address some of the main directions where the electrochemical processes are used today for synthesis of novel nanomaterials and nanostructures.

Dr. Stanko R. Brankovic during the lecture, Spring 2007.

The course is organized in two parts. The first one is an introduction into the fundamentals of physics and thermodynamics of electrified interface and their relation to the electrochemical systems at nanoscale. In particular, the phenomena like electrical double layer, reversible potential, adsorption and charge transfer across the electrochemical interface are discussed within the realm of nanoscale world. The second part of the course covers the most typical examples of electrochemical nanofabrication and nanosystems using the examples from the research papers and articles published in the peer reviewed journals, and also using the examples from Dr. Brankovic own research work. The students earn the credit for the final grade in the course through the work on their homework (15%, see example hw), projects (15%, see example project ) midterm (30%, see example midterm ) and final exam (40%). The approximate syllabus of the course is shown below; however, if particular students require deeper insight into specific area of the electrochemical science, the additional subjects to the syllabus can be added.
