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.
