Ikirahure gisanzwe ni ibikoresho bikingira ubushyuhe, bishobora gutwara amashanyarazi binyuze mu gushyira firime iyobora amashanyarazi (firime ya ITO cyangwa FTO) ku buso bwacyo. Iki ni ikirahure giyobora amashanyarazi. Gifite urumuri rugaragara kandi gifite urumuri rutandukanye. Biterwa n'ubwoko bw'ikirahure giyobora amashanyarazi gipfutse.
Ubwoko bwaIndorerwamo zitwikiriwe na ITOni 0.33/0.4/0.55/0.7/1.1/1.8/2.2/3mm hamwe n'ingano ntarengwa ya 355.6×406.4mm.
Ubwoko bwaIkirahure gitwikiriwe na FTOni 1.1/2.2mm ifite ingano ntarengwa ya 600x1200mm.
Ariko se isano iri hagati y’ubudahangarwa bw’impande zombi (square resistance) n’ubudahangarwa bw’ingufu (resistivity) n’ubudahangarwa bw’ingufu (conductivity) ni iyihe?
Muri rusange, igipimo gikoreshwa mu gusuzuma imiterere y'urukiramende rw'urukiramende ni ubushobozi bwo kudakora ku rupapuro, bugaragazwa naR (cyangwa Rs). Rbifitanye isano n'ubushobozi bw'amashanyarazi bwo guhangana n'urukuta rw'icyuma gitwara amashanyarazi n'ubugari bw'urukuta rw'icyuma gitwara amashanyarazi.
Muri iyo shusho,digaragaza ubunini.
Ubudahangarwa bw'urwego ruyobora icyuma niR = pL1 (dL2)
Muri formula,pni ubushobozi bwo guhangana n'ingufu za filime iyobora amashanyarazi.
Ku gice cya firime cyakozwe,pnadbishobora gufatwa nk'agaciro gahoraho.
Iyo L1 = L2, iba kare, uko ingano y'agace kaba kose, ubwiyongere bwayo ni agaciro kadahindukaR=p/d, ari na cyo gisobanuro cy'ubudahangarwa bwa kare. Ni ukuvuga,R=p/d, ishami rya Rni: ohm/sq.
Muri iki gihe, ubushobozi bwo guhangana n'urukuta rwa ITO muri rusange ni0.0005 Ω.cm, kandi icyiza ni0.0005 Ω.cm, hafi y’ubushobozi bwo guhangana n’icyuma.
Uburyo bwo guhagarara kw'imbaraga ni ugutwara imbaraga,σ= 1/p, uko amashanyarazi arushaho kuba menshi, ni ko amashanyarazi arushaho gukomera.
Saida Glass ntabwo ari umunyamwuga mu gushushanya ikirahure, ahubwo inashoboye no gufasha abakiriya gukemura ibibazo bya tekiniki mu gushushanya ikirahure.
