Abstract

fetched live from OpenAlex

Bonding of elastically strain-relaxed GaAs/InGaAs/GaAs heterostructures has been achieved on GaAs(001) substrates by the method of in-place bonding. Pseudomorphic heterostructures were patterned and a sacrificial AlAs layer was removed by selective etching. As etching proceeds and the GaAs/InGaAs/GaAs structure is released from the substrate, elastic strain relaxation occurs and the strain-relaxed structures are weakly bonded in-place to the substrate. The bond between the strain-relaxed structure and the substrate was then strengthened by annealing under conditions similar to those used for whole wafer bonding of GaAs. The degree of strain relaxation of the InGaAs layer is determined by the relative thickness of the GaAs and InGaAs layers. The increase in the in-plane lattice parameter of these bonded GaAs/InGaAs/GaAs structures is 0.3-0.4%.

Teacher imitation

Not 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.
