Abstract
Understanding the mechanism responsible for electron emission from ferroele ctrics is crucial for the design of ferroelectric cathodes. The mixed proce ss suggested in the model of Zhang et al. [J. Appl. Phys. 83, 6055 (1998)] appears to contain some contradictions. The most problematic is the coexist ence of two electron emission processes on the same surface in different el ectric fields.
