摘要
P the present invention relates to processes and devices for studying the phenomena of the surface by using the field effects. / p & & p & a device according to the invention comprises an enclosure 8, held under vacuum by a pump, which contains an emissive point by field effect 10 and a fluorescent screen 17. The enclosure 8 contains a cathode 16 and the electrodes 13, 14, 15. This device comprises electronic circuits which send simultaneously of the pulses of the periodic voltage on the tip 11 and the electrodes 13, 14, 15 and 16, so that the end of the tip is bombarded by the particles and heated, and which subject the tip 10 of the voltage pulses synchronized with the preceding ones. / p & & p & an application is the study of the kinetics of the phenomena of surface, such that the adsorption or desorption. / p
