Low Temperature Gap Measurement in Various Locations with Field Evaporation Method

DESCRIPTION

This research focuses on gap measurement at low temperatures, establishing stability across ten background signals (bkd's) in both the same and different spots. With approximately 70 bkd's collected per temperature, we observe consistent gap stability at both temperatures. Next steps involve replicating the measurements in alternative locations and performing single bkd assessments on a copper sample to investigate material transfer. We are also integrating alerts for breakdowns during the evaporation process as part of our ongoing investigation.

System II: LowTemperature In same spot In different spots • 10 bkd’s -> gap meas. -> 10 bkd’s … • approx. 70 bk’s per temperature • gap quite stable at both T • Next: do thesame in anotherspot (workingonit)
System I: FieldEvaporation • Done: new W tip (onebkd). Anité • Next: Cu sample, so wecan: • do single bkd’sonseveral spots and check material transfer • Esat in another spot • keeponwithevaporation (withbreakdown“alert”)
