Current Research and Scholarly Interests

My current research involves working on insulator-metal-transition oxides such as NbO2 and LaCoO3 to understand their switching physics in electrical devices compared to thermal switching, and use various electrical and materials characterization as well as novel in-situ spectroscopy techniques in my work. I am interested in their applications in memory selectors, ESD protection clamps, and brain-inspired computing.

As part of my PhD work, I have collaborated with both academia (Purdue, Rutgers, USC, Sandia NL, Lawrence Berkeley NL) as well as the industry (NGC, On Semi) outside of Stanford.

I have also completed a NAND pathfinding internship at Micron Technology where I used my knowledge of semiconductor device physics and process fabrication skills to design experiments and study the challenges of tier pitch scaling in 3D NAND. As part of the Process Integration team, I have collaborated closely with other Process teams as well as Device and TEM imaging labs.

    Translating the surging interest in neuromorphic electronic components, such as those based on nonlinearities near Mott transitions, into large-scale commercial deployment faces steep challenges in the current lack of means to identify and design key material parameters. These issues are exemplified by the difficulties in connecting measurable material properties to device behavior via circuit element models. Here we use the principle of Local Activity to build a model of VO2 / SiN Mott threshold switches by sequentially accounting for constraints from a minimal set of quasi-static and dynamic electrical and high spatial resolution thermal data obtained via in-situ thermoreflectance mapping. By combining independent data sets for devices with varying dimensions, we distill the model to measurable material properties and established device scaling laws. The model can accurately predict electrical and thermal conductivities and capacitances and locally active dynamics (especially persistent spiking self-oscillations). The systematic procedure by which we develop this model has been a missing link in predictively connecting neuromorphic device behavior with their underlying material properties, and should enable rapid screening of material candidates before employing expensive manufacturing processes and testing procedures.
