Abstract:
A method for assessing the quality of a tip of a scanning probe microscope (SPM) includes recording an SPM image, extracting a plurality of images of dangling bonds from the SPM image, feeding the extracted images of dangling bonds into a convolution neural network one image at a time, analyzing each of the plurality of images of dangling bonds using the convolution neural network, assigning each of the plurality of images of dangling bonds one of a sharp tip status or a double tip status, and determining whether the number of the plurality of images of dangling bonds of the SPM image assigned the double tip status exceeds a predetermined threshold. A method of automatically conditioning a tip of a scanning probe microscope (SPM) during imaging of a sample and a method of mass-producing atomistic quantum dots, qubits, or particular atom orbital occupation are also provided.
