用来当作电阻温度计的锗薄膜业已在液氦温度下做过试验。锗在真空下被沉积在绝缘的基片上,然后把银沉积在锗薄膜上作为欧姆接触,籍助于选择适当的沉积条件,就能容易地制造出具有所需要的电阻和合适的灵敏度的温度计。这些温度计具有快速响应时间,并能用于测量快速变化的表面温度。 Ge films used as resistance thermometers have been tested at liquid helium temperatures. Germanium is deposited on an insulating substrate under vacuum and the silver is deposited on the germanium film as an ohmic contact. By selecting the appropriate deposition conditions, a thermometer having the desired resistance and suitable sensitivity can be easily fabricated . These thermometers have fast response times and can be used to measure rapidly changing surface temperatures.
