抄録

A new technique for continuously detecting the slope of the Fowler-Nordheim plot has been developed. The system, which consists of analog signal processing circuits and lock-in amplifier, gives not only the slope of the Fowler-Nordheim plot but also the output proportional to the work function of a field emitter surface. The developed system was used to measure the change in work function of a field emitter surface during heating. Thermal desorption spectra from a Re field emitter covered with adsorbed residual gases has been obtained by differentiating the work function versus temperature curve. The thermal desorption peak assigned as a desorption of adsorbed hydrogen was detected at the heating temperature about 500 K. Some relatively small desorption peaks reflecting chemical reactions on emitter surface were also observed at higher heating temperatures.
