About

Role in the KNI

Matthew Hunt is the Assistant Director of Staff Research and Lead Microscopist for The Kavli Nanoscience Institute (KNI) at the California Institute of Technology. He directs research projects that are carried out by KNI technical staff, in collaboration with Caltech & non-Caltech PIs and student researchers, with the purpose of creating new nanofabrication techniques using the KNI's leading edge instrumentation. He leads the scientific side of the KNI SURF-the-WAVE Fellowships Program, which offers summer fellowships to non-Caltech undergraduate researchers, and also leads the Lab Resident Expert Program, which provides top lab users an opportunity to give back to the lab in the form of process recipe development and new ideas for general lab improvement. Matt also manages – and teaches users how to operate – the KNI's suite of microscopy equipment: transmission electron microscopes, scanning electron microscopes, focused ion beam systems, an atomic force microscope, and related sample preparation equipment.

Matt joined the KNI in 2014 after completing his PhD related to the high temperature oxidation of turbine engine materials, through which he developed expertise in a number of electron, ion and x-ray microscopy techniques. His research interests lie in the development of new lithography and microscopy techniques that utilize various beam species (e.g. helium ions, neon ions, gallium ions, electrons) and the application thereof to the kinds of novel materials and devices that are important to users of the KNI.

Education

Matt received his Ph.D. and M.S. in Materials Science & Engineering from the University of California, Irvine and a B.S. in Chemical Engineering from the University of Notre Dame.

Figure 4a-c from "Plasma-Etched Pattern Transfer of Sub-10 nm Structures Using a Metal–Organic Resist and Helium Ion Beam Lithography," depicting 5.4 nm wide lines of resist, spaced 17 nm apart, written with 35 keV helium ions on silicon, shown before etch in (a) plan view and (b) tilted view, then (c) after etch in titled view. All images were captured using 30 keV helium ion microscopy. As of publication in 2019, these represent the smallest features ever reactive-ion-etched into silicon, setting a new record for one of the world’s foremost nanofabrication benchmarks. https://pubs.acs.org/doi/10.1021/acs.nanolett.9b01911
