Achievement

IGERT-Lifechips fellow, Christopher Dunckle, studied the effects of changing the temperature in friction coefficient by using Friction Force Microscopy in a Variable Temperature AFM. Once the behavior is determined, it is possible to build on theorectial models that explain the results through phonon or electron interactions across the contact interface. During the experiments, Chris discovered a thermal heat flow issue within the field whereas a hot AFM tip and local contact area is unaccounted for and hope to resolve this issue by moving the AFM into an isothermal environment of a cryostat. This research is widely applicable as many fields are concerned with the friction of nano contacts including: cell biology, mechanical, material, and aerospace engineering, and Mems and Nems device construction. Through program, Chris investigated in several interdisciplinary labs. Eventually found one that would allow him to focus on this research that can be applicable in other disciplines.
