Laser Induced Oxidation and Defect Formation in 2D Materials

High throughput characterization and processing techniques are becoming increasingly necessary to navigate multivariable, data-driven design challenges for sensors and electronic devices.. In this talk, a high-throughput approach for designing and customizing 2D materials that enable novel, multifunctional properties is presented. This technique involves the use of laser-processing to locally-induce crystallization, oxidation, and defect formation in 2D materials such as transition metal dichalcogenides, modifying local electronic and optical properties. Coupled with high-throughput characterization, this allows for the rapid evaluation of structure-property relationships and subsequent device design. This same process can be implemented in a roll-to-roll configuration to allow for manufacturing of ultralow cost 2D sensor devices for a host of different sensing environments, including the detection of pathogens.
