Abstract
The nature of strain relaxation in GaP films grown on (100), (311)A, and (311)B GaAs by molecular beam epitaxy has been studied by transmission electron microscopy and atomic force microscopy. It is found that (100) GaP∕GaAs films develop surface undulations with twinning and cracking. (311)A GaAs provides good growth orientation for GaP films, producing flat surfaces and crack-free films. Similarly, (311)B GaP∕GaAs films do not develop cracks, however, the surface is rough. The anisotropy of cracking observed in GaP films has been discussed in terms of a lattice trapping theory. Twinning is an effective form of stress relaxation in GaP films. The features of the dislocation structure produced during relaxation have been discussed in terms of energy considerations. The data suggest that the equilibrium position of misfit dislocations is located in the softer substrate where the total energy of the system is a minimum. During relaxation, those dislocations which acquire larger kinetic energy can move over the small energy well and penetrate deeper into the substrate, in agreement with transmission electron microscope observations.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
