Graphite ifite imyenge ni iki? Imiterere, Imikoreshereze n'Ibyiza bya Semiconductor

Intangiriro: Impamvu Graphite ifite imyenge ifite akamaro mu gukora semiconductors

Uko inganda za semiconductor zigenda zigana ku nsinga zigezweho na semiconductors (nka SiC), ibisabwa mu bikoresho byarushijeho gukomera. Ubushyuhe bwinshi, isuku iri hejuru cyane, no kugenzura neza urujya n'uruza rwa gaze ni ingenzi cyane.

Nk’uko Ikigo Mpuzamahanga Gishinzwe Ingufu kibitangaza, ibikoresho bigezweho bigira uruhare runini mu gutuma ikoranabuhanga ry’ingufu n’ibikoresho bya semiconductor byo mu gisekuru gitaha rikoreshwa, cyane cyane mu by’amashanyarazi akoresha ingufu nyinshi.

Muri ibyo bikoresho, grafiti ifite utwenge yagaragaye nk'igisubizo cy'ingenzi cyo kugera ku ituze, uburinganire, no kunoza umusaruro.

Graphite ifite imyenge ni iki?

Grafite ifite imyenge ni ibikoresho bya karuboni byakozwe mu buryo bwa tekiniki bifite urusobe rw’imyenge ihujwe, bigatuma umwuka cyangwa amazi yinjira mu kirere mu gihe graphite ikomeza kugira imiterere yayo.

Bitandukanye na grafiti nini, grafiti ifite imyenge itanga:

● Ingufu zo kwinjira: ubusanzwe 10⁻¹² kugeza 10⁻¹⁴ m² (bitewe n'imiterere)

● Ubwinshi bw'ingufu: ubusanzwe 10%–30% (urwego rwakozwe mu buryo bwa tekiniki)

Ibi biyiranga bituma iba nziza cyane mu gukwirakwiza gaze no kugenzura ubushyuhe mu mikorere ya semiconductor.

Imiterere mito ya Graphite ifite imyenge

Imiterere ya karuboni

Grafiti ifite imyenge igizwe n'ibice bya karuboni bifatanye na sp², bitanga:

● Uburyo bwo gutwara ubushyuhe: 80–150 W/m·K (urugero rusanzwe)

● Ubushyuhe buhamye: kugeza kuri 3000°C mu kirere kidashyuha

 Imiterere y'Umwobo

Imikorere yayo ishingiye ku miterere y’imyenge y’ubuhanga:

● Ingano y'umwobo: ubusanzwe ni 1–100 μm

● Ubwinshi bw'imyenge ifunguye: ni yo ikoreshwa mu gutwara lisansi

● Ubuso: byongera uburyo bwo gukora reaction

Imiterere mito igena neza uburyo umwuka ugenda n'imikorere yawo bingana.

Ibyiza by'ingenzi bya Graphite ifite imyenge

1. Uburyo bwiza bwo kwinjira muri gaze

Imiyoboro y’imyobo igenzurwa ituma habaho gukwirakwiza gaze mu buryo bumwe, bigatuma habaho imikorere ihamye mu mikorere ya CVD na EPI.

2. Kurwanya ubushyuhe bwinshi

Grafiti ifite imyenge ikomeza kugira ubusugire kuri:

● >2000°C mu bidukikije bidafite umwuka cyangwa bidafite umwuka

● Guhinduka guke k'ubushyuhe

3. Gukomera cyane mu bya shimi

● kurwanya ingese

● Ihamye mu bidukikije bya halogen na gaze ikora neza

4. Yoroheje kandi ifite imiterere myiza

● Ubucucike: ubusanzwe 1.5–1.9 g/cm³

● Igipimo cyo hejuru cy'imbaraga hagati y'uburemere

5. Ubuziranenge bw'ibinyabutabire bipima ibice bibiri

● Ivu ririmo: <50 ppm (ubuziranenge buri hejuru)

● Ni ngombwa cyane ku buryo bwo kwanduzanya ibintu

6. Uburyo bworoshye bwo guhindura imiterere y'umubiri

Abakora bashobora gushushanya:

● Ingano y'umwobo

● Ubucucike

● Gushobora kwemererwa

Ibi bituma habaho kunoza imikorere yihariye, cyane cyane mu nganda zigezweho za semiconductor.

Imikoreshereze ya Semiconductor ya Graphite ifite Imyenge

Ikwirakwizwa rya gaze muri CVD na Epitaxy (EPI)

Graphite ifite imyenge ituma umwuka unyura mu buryo bumwe, ikongera ubugari bwa firime n'umusaruro wa wafer.

Gukura kwa PVT Crystal (SiC)

Ikoreshwa mu buryo bwo kugenzura ubushyuhe, ishyigikira iterambere rirambye rya kristu.

Dukurikije inyandiko za IEEE, ubushyuhe bungana ni ingenzi kugira ngo kristalo ya SiC ikure neza.

 Gukoresha imashini zisukura no gucunga imashini zisukura

● Uburyo bwo gukurura umwuka mu buryo buhamye

● Gukwirakwiza igitutu kimwe

 Ibice byo gucunga ubushyuhe

● Gutwara ubushyuhe neza

● Kugabanuka k'ubushyuhe

 Sisitemu zo kuyungurura no gukwirakwiza

● Gusukura gazi

● Ahantu hagenzurwa uburyo bwo gukwirakwiza

Graphite ifite imyenge vs Graphite ifite ubucucike bwinshi

Umwanzuro: Graphite ifite imyenge ituma habaho kugenzura neza inzira graphite nini idashobora kugeraho.

Nigute wahitamo Graphite ifite imyenge ikwiye?

 Ibipimo by'ingenzi byo gusuzuma:

● Ingano y'imyenge (urugero rwa μm) → igira ingaruka ku ikwirakwizwa rya gaze

● Ubushobozi bwo kwinjira mu mazi (m²) → bigena uburyo amazi anyuramo neza

● Ubuziranenge (urugero rwa ppm) → bugira ingaruka ku byanduza

● Uburyo ubushyuhe butwara (W/m·K) → bugira ingaruka ku igenzura ry'ubushyuhe

● Guhuza neza irangi (SiC, TaC)

Guhitamo neza bishobora kongera umusaruro, uburinganire, no kudahungabana kw'imikorere.

Imbogamizi n'Icyerekezo cy'Inganda

Nubwo grafiti ifite imyenge itanga ibyiza bisobanutse, imbogamizi zirimo:

● Uburyo bugoye bwo gukora

● Igiciro cyo hejuru ugereranije na grafiti isanzwe

Ariko, bitewe n'ibikoresho by'amashanyarazi bya SiC n'ingufu zishobora kuvugururwa, icyifuzo gikomeje kwiyongera.

Nk’uko Ikigo Mpuzamahanga Gishinzwe Ingufu kibitangaza, ibikoresho bigezweho bizaba ingenzi mu bikorwa remezo by’ingufu bizaza mu gihe kizaza.
