Ex-situ Proxies

Develop proxies for ex-situ characterization using empirical Structure-Property relationships

Correlate quantified RHEED patterns with ex-situ characterization

Example: doping concentration from XPS

Intensity maxima position observed to correlates with doping

Steps:

1. Run automated feature extraction on RHEED patterns (30 seconds)

2. Take top 3 features correlated with doping-composition from XPS and fit a linear regression.

3. Predict ex-situ characteristics (e.g., doping-composition) for subsequent samples
