Rotating RHEED data

AtomCloud is built to handle rotating RHEED data, simplifying in-situ characterization for commercial-scale MBE

AtomCloud deconvolves intensity and angular oscillation in rotating RHEED data to extract significant structural information.

t = 5s
t = 10s
t = 15s

Multi-component processing allows AtomCloud to generate all the same insights from stationary and rotating RHEED data

Time-averaging over the rotational period allows clustering while still using metrics from the original data.
  • Input to feature and metric extraction.
  • Choose high-symmetry representative snapshots within a cluster for pattern statistics.
  • Filter over the longest period detected, corresponding to the lowest-symmetry structure in the data.
  • Input to clustering - smooths over changes due to rotation only.
