Gukoresha RF excretion

1. Ni ingirakamaro ku gupfuka no gupfuka icyuma gikingira umuriro. Impinduka yihuta muri polarity ya electrode irashobora gukoreshwa mu gupfuka icyuma gikingira umuriro mu buryo butaziguye kugira ngo haboneke filime zikingira umuriro. Iyo isoko y'amashanyarazi ya DC ikoreshejwe mu gupfuka no gushyira filime ikingira umuriro, filime ikingira umuriro izabuza iyoni nziza kwinjira muri cathode, igakora urwego rwo gukusanya iyoni nziza, rushobora kwangirika no gushya. Nyuma yo gushyira filime ikingira umuriro kuri anode, electroni zirabuzwa kwinjira muri anode, bigatuma anode ibura. Iyo ukoresheje isoko y'amashanyarazi ya RF kugira ngo upfuke filime ikingira umuriro, bitewe n'uko polarity ya electrode isimburana, charges nziza zikusanyirijwe kuri cathode mu gice cya mbere cy'uruziga zizakurwaho na electron mu gice cya kabiri cy'uruziga, kandi electron zikusanyirijwe kuri anode zizakurwaho na iyoni nziza. Inzira inyuranye mu gice cya kabiri cy'uruziga ishobora gukuraho charges nyinshi kuri electrode, kandi inzira yo gusohora umuriro ishobora gukomeza uko bisanzwe.

2. Ama-electrode afite frequency nyinshi akora self bias. Mu gikoresho cya RF gifite imiterere ya electrode itambitse, ama-electrode afite frequency nyinshi mu ruziga akoresha capacitive coupling matching abyara self bias voltage. Itandukaniro rinini riri hagati y'umuvuduko wa electron migration n'umuvuduko wa ion migration mu gusohora bituma electron zigera ku muvuduko mwinshi w'ingendo mu gihe runaka, mu gihe umuvuduko wa ion utinda utera kwegerana. Ama-electrode afite frequency nyinshi aba afite potential mbi muri buri ruziga, bigatuma habaho volteji mbi ku butaka, ari nabyo bituma self bias ya electrode ifite frequency nyinshi.

Uburyo bwo kwishyiramo ibintu bukorwa na electrode yo gusohora RF bwihutisha ikwirakwizwa rya ion rya electrode ya cathode kugira ngo ikomeze gusohora electron za kabiri kugira ngo ikomeze gusohora, kandi uburyo bwo kwishyiramo ibintu bugira uruhare rusa n'igabanuka rya cathode mu gusohora urumuri rwa DC. Nubwo hakoreshejwe ingufu za RF, gusohora ibintu bishobora kuba bihamye bitewe n'imbaraga zo kwishyiramo ibintu zikorwa na electrode ifite frequency yo hejuru zigera kuri 500-1000V.

3. Gusohora umurongo wa radiyo bigira uruhare runini mu gusohora urumuri rw'umuvuduko w'ikirere no gusohora urumuri rw'urumuri rw'amashanyarazi nyuma.
