Solo write-ups on topics I've been digging into outside of coursework.
An overview of how nitrogen-vacancy defects in diamond act as room-temperature quantum sensors. Covers the underlying spin physics, how Optically Detected Magnetic Resonance reads out that spin state, and the fabrication hurdles standing between lab demos and deployable magnetometers.
A proposed reactor design and growth recipe for directly synthesizing wafer-scale 2D hexagonal boron nitride, aimed at producing self-limiting monolayers with built-in single-photon emitters — sidestepping the scalability limits of exfoliation and traditional CVD.
Group fabrication labs from UCSB's ECE 120 semiconductor devices sequence.
Full fabrication and electrical characterization of MOSFETs, diodes, MOS capacitors, and TLM test structures built from scratch in UCSB's cleanroom, from photolithography through I-V and C-V analysis.
Design, fabrication, and testing of 3-, 5-, and 7-stage NMOS ring oscillators using a four-mask process, comparing measured oscillation frequencies against theoretical predictions.
