Abstract

Summary form only given. Effect of spontaneous polarization on the ferroelectric electron emission (FEE) is investigated by using ferroelectric materials having different value of P/sub s/. G. Rosenman et al. (1993) suggested that the screening electrons can be emitted from the bare surface of ferroelectric materials by changing or reversing P/sub s/ in a short time. On the other hand, Puchkarev et al. (1995) pointed out that the surface plasma plays an important role for the strong electron emission. In this paper, we tried to make this controversy more clear.
