Nanoscale coherent light sources on GaAs and Si using single rolled-up InGaAs/GaAs quantum dot microtubes
Bibliographic record
Abstract
In this report we study the nanoscale coherent light sources on GaAs and Si using single rolled-up InGaAs/GaAs quantum dot microtubes. Such microtubes are formed by self-rolling of coherently strained InGaAs/GaAs quantum dot heterostructures through controlled release from their host substrates [1-3]. We have developed a substrate-on-substrate transfer process [3] and realized nearly defect-free quantum dot microtubes on Si that were not possible before. Emission characteristics of InGaAs/GaAs quantum microtubes were studied using micro-photoluminescence spectroscopy at 300 K. A typical emission spectrum measured from the freestanding region of a microtube without any intentional surface corrugations (inset) is shown in Fig. 3(a) (solid line), which is characterized by a sequence of regularly spaced optical resonance modes superimposed on a broad quantum dot emission spectrum (dotted line). These resonance modes arise from photons circulated around the periphery of the microtube by total internal reflections.

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.
