Abstract
The temperature dependence of field-stimulated exoelectron emission (FSEE) on a clean W tip was investigated. The increase of the electron emission at the moment of reapplication of the tip voltage was observed at the temperatures 200–450 K. This emission property was similar to the storage effect of exoelectron emission from Al tips reported previously. [Appl. Phys. Lett. 53, 626 (1988).] However, the emission intensity was independent of the voltage interruption period. The change in work function was also indicated at the temperature where FSEE was observed. The FSEE on W tips observed in this study was explained by the exoelectron emission during the surface reconstruction of W{001} and/or W{031} triggered by the high electric field.
