Abstract
The work functions of a 211 and a 310 plane on one tungsten crystal were determined using Fowler's method. Since the time necessary thoroughly to outgas the crystal would have been very great, the photocurrents characteristics of the clean surfaces were determined from data obtained soon after the crystal was flashed at about 2200°C. The work function of the 211 plane was found to be 4.50 volts and that for the 310 plane to be 4.35 volts.Keywords
