THE CONTACT POTENTIAL DIFFERENCE BETWEEN TUNGSTEN AND NIOBIUM

Journal Article · · Brit. J. Appl. Phys.

Contact potential difference measurements were made between tungsten amd niobium foil using both the Kelvin and the displacement of the retarding potential line techniques in ultra-high vacuum conditions. Values of 0.18 plus or minus 0.04 and 0.17 plus or minus 0.03 v were obtained, respectively, leading to a mean work function for niobium of 4.37 plus or minus 0.03 ev. (auth)
