AB Super-resolution (SR) methodologies allow the construction of highresolution images from several noisy low-resolution images. This methodologycan be applied to overcome the inherent resolution limitation and improve theperformance in digital imaging of scanning transmission electron microscopes(STEM). Here we apply SR to column resolved images of a monocrystallineGaAs/InAs quantum dot covered by a GaAsSb capping layer. Series of 8 imageswith a dwell time of 1s were taken to apply SR. The improvement of the SRimages has been evaluated in terms of SNR and spatial reliability by comparisonof images captured with a dwell time of 8s. The results indicate that the SRtechnique emerges as a remarkable and powerful tool for the improvement of thequality of the STEM imaging.
