Abstract:
Quantum materials provide responses and states of matter with no classical analogues. As such they offer opportunities to create an array of platforms for future devices crucial to human health, energy efficiency, communications and imaging. In this talk I will discuss our use of graphene for biosensing and a Mott Insulator for controlling charge on the Nanoscale. Using the relativistic electrons in graphene we have developed a new platform for multiplexed, rapid, easy to use detectors of biological analytes. I will discuss the fabrication and design issues involved resulting in our demonstration of the detection of antibiotic resistant bacteria, decease biomarkers in saliva, opioids in waste water and respiratory infection at clinically relevant levels. In the second half I will discuss how review our discovery of modulation doping in 2D materials. Specifically the ability to use RuCl3 as a crystalline acceptor to induce large and local charge in other 2D systems.

Bio:
Kenneth Burch has been a Professor of Physics at Boston College since 2014 running the Laboratory for Assembly and Spectroscopy of Emergence (LASE). Before arriving at BC, he was an assistant professor at the U. of Toronto for 5 years. He is a former Director’s fellow at Los Alamos National Laboratory where he performed ultrafast spectroscopy with A. Taylor, and was a graduate student of D. Basov studying the optical properties of magnetic materials at UCSD. He has made seminal contributions to the development of novel techniques to understand and exploit quantum materials. This includes discovering the Axial Higgs Mode in a Charge Density Wave, the colossal bulk photovoltaic effect in a Weyl semimetal, modulation doping in 2D materials, fractional spin excitations in a potential Kitaev spin liquid and he developed cutting edge biosensors based on graphene. His group also developed a cleanroom in a glovebox where all fabrication and heterostructure preparation is performed. For his work he has received a number of awards including the Lee-Asheroff-Riuchardson Prize and the APS GMAG best dissertation award. The work also resulted in publications in high impact journals including: Nature, Advanced Materials, Nano Letters, ACS Nano, PRX, Biosensors and Biolectronics, multiple patents and is supported by NIH, NSF, DOE, ONR, AFOSR, ARO, BARDA, GRIP molecular and GINER Inc.
