    Abstract: A combined surface topography and spectroscopic analysis instrument comprises a scanning tunnelling microscope tip (12); and a sample carrier (58) which supports a sample (10) so that a surface thereof to be analysed is presented towards the tip (12). The sample carrier (58) and the tip (12) are relative movable to enable the distance between the tip (12) and the surface to be varied in use and the sample surface to be scanned in two dimensions by the tip (12). An electron analyser is positioned to detect electrons from the tip (12) which have been back-scattered off the sample surface. A voltage controller (59) enables selective operation of the tip (12) in a first voltage range in scanning tunnelling mode, to enable spatial resolution imaging of the sample surface, and in a second, higher, voltage range in electron field emission mode whereby to permit the electron analyser to analyse the back-scattered electrons. The electron analyser is positioned so as to detect back-scattered electrons travelling at an angle of less than 20 DEG with respect to the sample surface.

    Abstract: This disclosure relates to automatic determination of locations of one or more closely spaced donor atoms implanted into a semiconductor crystal lattice. A processor receives image data generated by a scanning tunnelling microscope (STM). The image data is indicative of a tunnelling current between a scanning tip and the crystal lattice at multiple image locations. The processor applies a trained machine learning model to the image data to determine a classification into one of multiple candidate configurations of the one or more donor atoms. The multiple candidate configurations relate to different locations of the one or more donor atoms in the semiconductor crystal lattice. Based on an output of the trained machine learning model, the processor determines the location of the one or more donor atoms in the semiconductor crystal lattice.

    Abstract: A method for determining a nucleotide sequence of a nucleic acid is provided that includes contacting the nucleic acid with a series of labeled oligonucleotides for binding to the nucleic acid, wherein each labeled oligonucleotide includes a known nucleotide sequence and a molecular nanocode. The nanocode of an isolated labeled oligonucleotides that binds to the nucleic acid is then detected using SPM. Nanocodes of the present invention in certain aspects include detectable features beyond the arrangement of tags that encode information about the barcoded object, which assist in detecting the tags that encode information about the barcoded object. The detectable features include structures of a nanocode or associated with a nanocode, referred to herein as detectable feature tags, for error checking/error-correction, encryption, and data reduction/compression.
