Gavin Scott
Gavin D. Scott, Ph.D.
Senior Scientist
Electrical Engineering & Computer Science
New York

Dr. Scott has a background in condensed matter physics with expertise in the design and fabrication of nanoscale semiconductor devices and micromagnetic structures that serve as tunable models for probing complex electronic and magnetic interactions. He has extensive experience investigating charge transport at cryogenic temperatures in nanostructured devices allowing for the study of strongly interacting charge carriers responsible for novel material properties such as superconductivity.

Dr. Scott has worked with several different custom designed cryogenic systems, including Helium-4, Helium-3, and dilution refrigerators, while employing a variety of transport characterization techniques including AC and DC transport, magnetoresistance, pulse spectroscopy, and differential conductance using lock-in detection. He is also experienced with related equipment including superconducting magnets, helium leak detectors, and vacuum systems incorporating diffusion, turbo, sublimation, mechanical, and cryo pumps. He is highly skilled with data acquisition via data flow programming and quantitative data analysis techniques, and he has worked extensively with finite-element based modeling for micromagnetic simulations.

Prior to joining Exponent, Dr. Scott worked as a research scientist at Nokia Bell Laboratories where he was a principal investigator for a low temperature experimental research effort involving highly correlated electron states leading to collective effects (e.g. Kondo effect and phase transitions) in magnetic nanosctrucutres. He additionally advised management on quantum computing methodologies and quantum information processing applications aligned with their business strategies.

Dr. Scott worked as a postdoctoral research scientist at Rice University after receiving his Ph.D. in physics at UCLA where he studied charge transport in metallic nanogap devices, single molecule transistors, and electrostatically defined semiconductor quantum dots. He has gained broad practical experience with a large range of semiconductor and nanofabrication processing techniques including electron beam and UV lithography, thin film metallization, and wet and dry etching processes. He also has considerable experience with a variety of characterization techniques including SEM, AFM, and STM.
