Christina L. McGahan

Cleanroom

Overview:

Christina is interested in applying nanofabrication techniques to control the properties of materials as well as use this precise control of materials and their properties to help researchers solve challenging nanoscale scientific problems in areas ranging from medicine and biology to chemistry, physics, engineering, and beyond. She has experience with lithography, thin film deposition, active plasmonics, optical spectroscopy, and using scanning probe microscopy (AFM/KPFM/EFM) to probe 2D material, organic semiconductor, and quantum dot field effect transistors. In VINSE, Christina manages and trains users as well as Tech Crew members on the Angstrom Multimode and Resistive deposition systems, tube furnaces, electrical probe station, Raith EBL, Heidelberg laser writer, and 3D printers. She additionally developed and leads workshops on microfluidic device fabrication. Christina also leads the facilitation of cleanroom teaching and outreach in VINSE including microfluidics, solar cells, and 2D materials.
