Characterisations include noise amplitude at various drive currents and back gate voltages, Hall voltage measurements at various magnetic fields and back gate voltages, 2-wire voltage measurements with back gate voltage, and an SEM image used in publications/dissemination. The data files are named according to a convention that indicates to which wire width each file corresponds. Data in figures 7 and 8b of the associated paper are based on all of the complete sets of data for each of the wire widths. 2019-10-08 University of Bath public RightsHolder University of Bath Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 EP/R007160/1 Graphene Nanosensors for Scanning Hall Microscopy and Susceptometry Lloyd's Register Foundation https://doi.org/10.13039/100008885 G0086 Graphene-Hall-effect nanosensors to optimise high current superconducting tapes for applications in ‘smart’ power grids European Cooperation in Science and Technology https://doi.org/10.13039/501100000921 CA16218 Nanoscale Coherent Hybrid Devices For Superconducting Quantum Technologies (NANOCOHYBRI) cent_nan Data was collected using: - a Stanford SR380 Lock-in amplifier for 2-wire FET measurement voltage and current data - translating to a resistance; - a Keithley 2450 SMU for Hall voltage data; - a Keithley 2400 SMU for back gate voltage applied data and gate leakage current data; - a HP3561A DSA for voltage noise amplitude data. The Hall probe array (Hall probes being the intersection of two equal width wires varying from 50nm to 1500nm) is glued and wire bonded into a headless package which is then placed in an oxford cryostat insert with electrical connections to the instruments which are then connected to the controlling PC. The insert is inserted into the cryostat and sealed. A Labview program was used to create the automated collection data sets. Where data was not automatically collected, this was taken manually off the above-mentioned instrument's screens and noted down in the previously detailed laboratory book. Data was copied and stored here for electronic storage. All data was collected under room temperature and 10-6 mbar pressures. The magnetic field is created by a 35mT electromagnet whose power is supplied by an 8A Kepco power supply. Aside from manual datasets, the power supply is automatically operated from a Labview program. All data is in its raw form as taken from the measuring instruments. A MATLAB file for the processing of the noise data acquired from the DSA is included in this repository. MATLAB is required for the code and manually copied electronically stored data. SEM data for the 85nm in the illustratory figure 9 is provided in the raw SEM file formats and TIF file format. 2018-04-01 2018-11-24 en 1 10.15125/BATH-00587 https://doi.org/10.1038/s41598-019-50823-8 pub open
