What is Low-macroscopic-field Electron Emission from Piezoelectric Thin Films and Crystals about?
Low-macroscopic-field (LMF) electron emission is an interesting and still somewhat enigmatic phenomenon. It occurs under conditions when the electric field estimated from the macroscopic device geometry is by orders of magnitude lower than the local field value Â/10 7 V cm (1 necessary to provide a sufficient transparency of the potential barrier for tunneling electrons. The mechanisms that convert the LMF into a high local field can range from trivial field enhancement caused by surface roughness to more intricate mechanisms, which are partly not well understood. We have developed and prepared field emitters based on piezoquartz single crystals as well as on textured thin films of piezoactive compounds ZnO, ZnS, CdS, Zn x Cd 1(x S, ZnSe, CdSe, SiO 2 and tested them in flat diode cells and in Mueller's field emission microscopes. All the cathodes generate electron emission in electric fields Â/10 5 V cm (1 as determined from the macrogeometry of the devices. A remarkable feature is the high emission current stability at j E/1 A cm (2 even under vacuum Â/10 (5 Torr. The cathodes have been utilised to make prototypes of flat matrix displays with cathodoluminescent screen brightness u
