Adrian Gozar's picture
Research Scientist in Applied Physics

Adrian’s research encompasses a range of areas and involved the use of several experimental techniques. The focus was, however, always on the understanding of collective electronic behavior in complex materials and of key aspects related to materials science, synthesis and exploitation of their functional behavior. Adrian received his Ph.D. in physics in 2004 from the University of Illinois at Urbana-Champaign. From 1999 to 2004, he was de facto based at Bell Laboratories in New Jersey. His studies at Bell were mostly focused on magnetism (e.g. quantum effects in low dimensions, disorder, frustration, light coupling mechanism to magnetic excitations) and various aspects of correlated electron physics. In 2004 Adrian moved on to work as a Goldhaber Fellow in the Oxide Molecular Beam Epitaxy group at Brookhaven National Lab. The research themes pursued revolved around superconductivity (e.g. mechanism, competing orders, dimensionality) and the physics of surfaces and interfaces (e.g. structure, interface superconductivity, routes for Tc enhancement, disorder effects). In 2010 Adrian received the Early Career Award from the U.S. Department of Energy and he used that opportunity to design and build novel instrumentation for performing optics at the nano-scale in a variable temperature environment using a cryogenic Scanning Near-Field Optical Microscope. This project was aimed at studying competing phases in correlated systems (e.g. phase transitions, role of intrinsic/extrinsic inhomogeneities) and of emergent phenomena associated with surfaces and buried interfaces in artificial nano-structures and devices. Starting in 2015 this effort continues in the Applied Physics Department at Yale University and is complemented by the capabilities and surface sensitivity of a Low Energy Electron Microscopy.
