Electromechanical Actuators Using Two-Dimensional (2D) Materials

We are sorry, this position has been filled.

The summer student will design, build and test electromechanical actuators using graphene, graphite, and boron nitride. Responsibilities will include (1) harvesting 2D materials (mechanical exfoliation of 2D materials), documenting 2D materials (imaging samples with an optical microscope); (2) characterizing materials (scanning with an atomic force microscope, and collecting / analyzing Raman data on the samples); (3) fabricating materials into device architectures of the students' design (using stacking / transfer techniques and tools, and designing electron beam lithography patterns using AutoCAD - a graduate student in our group will complete any fabrication that requires cleanroom access); and (4) testing and characterizing the behavior of the NEMS actuators for redesign. The goal of this project is to eventually demonstrate a graphene based NEMS switch with an extremely high on-off ratio, and to develop the proposed material system for other on-chip actuation-based sensing and signaling applications (both optical and electrical). The summer student will be expected to report on their results at the end of the summer in a poster presentation.
