Gushakisha uburyo bugenda bwiyongera muguhindura ingufu zizuba byatumye habaho ubushakashatsi burenze silicon gakondo ishingiye kuri pn ihuza izuba. Inzira imwe itanga icyizere iri muri selile yizuba ya Schottky, itanga uburyo bwihariye bwo kwinjiza urumuri no kubyara amashanyarazi.
Gusobanukirwa Ibyingenzi
Imirasire y'izuba gakondo yishingikiriza kumasangano ya pn, aho ikarishye nziza (p-ubwoko) kandi ikarishye nabi (n-ubwoko) igice cya kabiri. Ibinyuranye, izuba rya Schottky diode ikoresha ibyuma-semiconductor ihuza. Ibi birema inzitizi ya Schottky, ikorwa nurwego rutandukanye rwingufu hagati yicyuma na semiconductor. Umucyo ukubita selile ishimisha electron, ibemerera gusimbuka iyi bariyeri no gutanga umusanzu w'amashanyarazi.
Ibyiza bya Schottky Diode Imirasire y'izuba
Imirasire y'izuba ya Schottky itanga ibyiza byinshi kurenza selile gakondo ya pn:
Gukora neza-Gukora neza: Utugingo ngengabuzima twa Schottky muri rusange tworoshe gukora ugereranije na selile ya pn ihuza, birashoboka ko byatuma umusaruro muke ugabanuka.
Gutezimbere Umucyo: Guhuza ibyuma muri selile Schottky birashobora kunoza imitego yumucyo muri selile, bigatuma urumuri rwinjira neza.
Ubwikorezi bwihuse bwihuse: Inzitizi ya Schottky irashobora koroshya kugenda byihuse bya electroni yakozwe nifoto, birashobora kongera imikorere ihinduka.
Ubushakashatsi bwibikoresho bya Solar Solar
Abashakashatsi barimo gushakisha byimazeyo ibikoresho bitandukanye byo gukoresha mu zuba ry’izuba rya Schottky:
Cadmium Selenide (CdSe): Mugihe ingirabuzimafatizo za CdSe Schottky zerekana imikorere yoroheje hafi 0,72%, iterambere mubuhanga bwo guhimba nka electron-beam lithographe itanga ibyiringiro byiterambere.
Nickel Oxide (NiO): NiO ikora nk'ibikoresho byizewe byubwoko bwa p mu ngirabuzimafatizo za Schottky, bigera ku bikorwa bigera kuri 5.2%. Ibikoresho byayo bigari byongera urumuri no gukora muri rusange.
Gallium Arsenide (GaAs): Ingirabuzimafatizo za GaAs Schottky zerekanye imikorere irenga 22%. Ariko, kugera kuriyi mikorere bisaba ibyuma byubatswe neza-insulator-semiconductor (MIS) hamwe na oxyde igenzurwa neza.
Ibibazo hamwe nicyerekezo kizaza
Nubushobozi bwabo, Schottky diode selile izuba ihura nibibazo bimwe na bimwe:
Kwiyunga: Kwiyongera kwa elegitoroniki-mwobo muri selire birashobora kugabanya imikorere. Ubundi bushakashatsi burakenewe kugirango ugabanye igihombo.
Gukwirakwiza Uburebure bwa Barrière: Uburebure bwa bariyeri ya Schottky bugira ingaruka zikomeye kumikorere. Kubona impirimbanyi nziza hagati yinzitizi ndende yo gutandukanya neza kwishyurwa ninzitizi ntoya yo gutakaza ingufu nkeya ni ngombwa.
Umwanzuro
Imirasire y'izuba ya Schottky ifite imbaraga nyinshi zo guhindura imirasire y'izuba. Uburyo bwabo bworoshye bwo guhimba, kongera ubushobozi bwo kwinjiza urumuri, hamwe nuburyo bwihuse bwo gutwara ibintu bituma bakora ikoranabuhanga ryiza. Mugihe ubushakashatsi bwimbitse muburyo bwogutezimbere no kugabanya ingamba zo kugabanya ingufu, dushobora gutegereza kubona izuba ryizuba rya Schottky diode rigaragara nkumukinnyi ukomeye mugihe kizaza cyo kubyara ingufu zisukuye.
