![عکس صفحه اول مقاله: Low-voltage pulse exciting electron emission from ferroelectric copolymer film cathode: Role of film thickness and emission stability Low-voltage pulse exciting electron emission from ferroelectric copolymer film cathode: Role of film thickness and emission stability](/preview/png/5368271.png)
Ferroelectric copolymer thin films P(VDF-TrFE) are used as a ferroelectric cathode for investigation of their electron emission properties. This ferroelectric copolymer films with different thicknesses are deposited by spin-coating method, and then the annealing process is carried out to improve the crystallinities of as-deposited copolymer films. The measurement results of ferroelectric electron emission showed that the copolymer P(VDF-TrFE) films had a desired ferroelectric electron emission ability excited at low-voltage pulse, and its peak emission current can reach to be â¼1.3 μA when the pulse voltage is 280 V. In addition, the effect of film thickness on electron emission property and emission stability of copolymer thin film P(VDF-TrFE) are discussed.
