A new course in Nanofabrication and Nanocharacterization was developed and offered for the first time in Spring 2017. This course is intended for first year graduate students interested in the experimental practice of nanotechnology. In the context of a hands-on laboratory experience, students gain familiarity with both top-down and bottom-up fabrication and characterization technologies. This is achieved through the realization of a variety of micro- and nanoscale structures and devices that can exhibit either classical or quantum effects at the small scale. Although concepts relevant to the laboratories are emphasized in lecture, it is expected that students will already have been exposed to many of the underlying theoretical concepts of nanotechnology in previous courses. It is our intention to offer this course on a yearly, ongoing basis.
Topics include optical and electron-beam lithography, physical vapor deposition, chemical and plasma etching, self-assembly, quantum dots, and electron microscope and scanning probe characterization techniques. These technologies will be exploited to fabricate and characterize micro- and nanodevices and systems including graphene-based electronic transistors, phase-separated block copolymers, quantum dot systems, microelectromechanical systems, and microfluidic devices.
As mentioned above, the goal of this course is to give students a hands-on laboratory experience to complement their theoretical knowledge of nanoscience and nanotechnology. Major objectives include giving students a working understanding of:
- The unit processes utilized in the fabrication of micro- and nanostructures
- Process synthesis techniques enabling the combination of unit processes to produce complex micro- and nanostructures
- Characterization techniques used to understand the behavior of micro- and nanostructures
- The correlations between observed behavior of micro- and nanostructures and their theoretical underpinning
