Sapphire substrate with electric contact




sample biasing.
Substrate size - 24х19.3x0.5mm.
Spring made from steel, grade 2, diameter -0.3mm.

Sample preparation procedure:
  • Take a clean substrate. Cut off a strip of a double-sided adhesive tape, slightly wider than the sample.
  • Stick the adhesive tape to the substrate, smooth its surface out with the back of the tweezers to remove air bubbles between the substrate and the adhesive tape.
  • Put the sample, for example, a graphite plate (HOPG), on the adhesive tape and carefully press it with tweezers in several places.

Note: After the sample is fixed on the substrate, a noticeable vertical drift of the sample can occur within one hour (due to the slow relaxation of sticky tape). This drift should be taken into account. If a minimal drift is required due to the nature of the investigation, prepare the sample beforehand (at least in an hour before the investigation).
