Focus Areas
Selected threads of work — control systems, methodology, simulation, and analysis.
Control System
TDL Dual-Chuck Motion Control
ACSPL+ programming for a dual-chuck laser and machining platform — coordinate capture from confocal touch routines, quadratic depth-targeting correction, and automated layer-target generation.
Methodology
Stress-Based Diamond Splitting
A separation approach built around controlled lateral crack-tip coalescence along {100} planes, in contrast to uncontrolled {111} cleavage — benchmarked conceptually against Infineon's Cold Split process for SiC, with comparative diagrams covering ultrasonic, UV-ozone, and molten-salt routes.
Structural Simulation
Graphite–Diamond Eigenfrequency Study
COMSOL eigenfrequency modeling of a diamond–graphite–diamond sandwich (250 / 75 / 250 µm) to test whether graphite resonance can generate enough shear to split diamond plates, using a full 6×6 anisotropic stiffness model for graphite.
Experiment
Arrhenius Etching Kinetics
A 3×3 factorial study across temperature and time to extract etching activation energy, paired with roughness tracking (Sa, Sz) to connect kinetics to surface outcome.
Analysis
Surface Treatment & Termination Survey
ANOVA comparison across surface-treatment process groups (AB, MS, UV-Ozone, WVE POR), alongside a DFT literature review comparing hydrogen, oxygen, and sulfur terminations on diamond (100)/(001) surfaces.
Software
Laser Recipe Templating Engine
Jinja2 templates that generate JSON process recipes, with quadratic depth-correction for damage-layer targeting and guard conditions for minimum slab thickness and layer ordering.
