Fig. 5: Controlled growth process of high-density quantum dots (QDs).
From: Machine-learning-assisted and real-time-feedback-controlled growth of InAs/GaAs quantum dots
Experiment with the “high” label as the target. Blue lines: the QD formation time. Yellow lines: the In shutter closing time. a Substrate temperature during growth. The reflection high-energy electron diffraction (RHEED) image (b) captured at 200th frame after growth; c before the QD formation; d after the QD formation; e before the end of the growth; f the 2 μm × 2 μm atomic force microscope (AFM) image of the sample; the prediction results of (g) the “QDs model” and (h) the “density model”. Dots: probability statistics of different labels based on the model results. Lines: running average plots of dots. Source data are provided as a Source Data file.
