Chii Chinonzi Porous Graphite? Zvimiro, Mashandisirwo & Mabhenefiti eSemiconductor

Nhanganyaya: Nei Graphite Iine Maburi Inokosha Mukugadzira Semiconductor

Sezvo kugadzirwa kwema semiconductor kuri kufambira mberi kuenda kuma nodes epamusoro uye ma compound semiconductors (akadai seSiC), zvinodiwa nezvinhu zvave kuramba zvichiwedzera kuoma. Kugadzikana kwekupisa kwakanyanya, kuchena kwakanyanya, uye kudzora kuyerera kwegasi kwakanyatsojeka kwave kukosha.

Sekureva kweInternational Energy Agency, zvinhu zvepamusoro zvinoita basa guru mukugonesa tekinoroji yesimba rechizvarwa chinotevera uye matekinoroji e semiconductor, kunyanya mumagetsi emagetsi anoshanda zvakanyanya.

Pakati pezvinhu izvi, girafiti ine maburi yakabuda senzira yakakosha yekuwana kugadzikana, kufanana, uye kuvandudza goho.

Chii Chinonzi Porous Graphite?

Graphite ine maburi chinhu chakagadzirwa nekabhoni chine network inodzorwa yemaburi akabatana, zvichiita kuti gasi kana mvura ipinde ukuwo ichichengetedza hunhu hwemukati hwegraphite.

Kusiyana negrafiti yakakora, girafiti ine porous inopa:

● Kupinda kwemvura: kazhinji 10⁻¹² kusvika 10⁻¹⁴ m² (zvichienderana nechimiro)

● Kuboorwa kwemvura: kazhinji 10%–30% (nzvimbo dzakagadzirwa)

Hunhu uhwu hunoita kuti ive yakanaka pakupararira kwegasi uye kudzora kupisa mumabasa e semiconductor.

Magadzirirwo eGraphite ine Maburi Madiki

Maumbirwo eKabhoni

Graphite ine maburi ine maburi ecarbon akabatanidzwa ne sp², zvichipa:

● Kutenderera kwekupisa: 80–150 W/m·K (nzvimbo yakajairika)

● Kugadzikana kwekupisa: kusvika ku3000°C mumhepo isina kusimba

 Maumbirwo ePore

Kushanda kwayo kunoenderana nehunhu hwemaburi akagadzirwa:

● Saizi yeburi: kazhinji 1–100 μm

● Kuvhurika kwemaburi: chinhu chikuru chekutakura mafuta

● Nzvimbo yepamusoro: inowedzera maitiro ekugadzirisa

Microstructure inosarudza zvakananga kufanana kwekufamba kwegasi uye kushanda zvakanaka kwemaitiro.

Mabhenefiti Akakosha eGraphite Ine Maburi

1. Kupinda Kwemhepo Kwakanaka Kwegasi

Manetwork epore akadzorwa anogonesa kugoverwa kwegasi kwakafanana, zvichivandudza kuenderana kwekuisa gasi mumagadzirirwo eCVD neEPI.

2. Kuramba Kupisa Kwakanyanya

Graphite ine maburi inochengetedza kugadzikana pa:

● >2000°C munzvimbo dzisina kusimba kana dzisina kusimba

● Kuchinja kushoma kwekupisa

3. Kugadzikana Kwemakemikari Kwakakwirira

● kudzivirira ngura

● Yakagadzikana munzvimbo dzine halogen uye dzinoita gasi rinoita reactive

4. Huremu hwakareruka uye hwakavimbika pakuvaka

● Kuwanda: kazhinji 1.5–1.9 g/cm³

● Simba guru pakati pehuremu

5. Kuchena kweSemiconductor-Grade

● Kuwanda kwedota: <50 ppm (magiredhi ekuchena kwakanyanya)

● Zvakakosha pakuita kuti zvinhu zvisanyanya kusvibiswa

6. Kugadziriswa KwemaPorosity

Vagadziri vanogona kugadzirisa:

● Saizi yeburi

● Kuwanda kwehuwandu

● Kutendeseka

Izvi zvinogonesa kugadzirisa maitiro akasiyana, kunyanya mukugadzira zvinhu zvemhando yepamusoro.

Mashandisirwo eSemiconductor ePorous Graphite

Kugoverwa kweGasi muCVD & Epitaxy (EPI)

Graphite ine maburi inoita kuti gasi rifambe zvakanaka, zvichiita kuti ukobvu hwefirimu huve hwakaenzana uye kuti wafer ibude zvakanaka.

Kukura kwePVT Crystal (SiC)

Inoshandiswa mumasisitimu ekudzora thermal field, ichitsigira mamiriro ekukura kwekristaro akasimba.

Sekureva kweIEEE publications, kufanana kwekupisa kwakakosha pakukura kweSiC crystal yemhando yepamusoro.

 Kubata Machuki eVacuum & Wafer

● Kunyudza kwevacuum kwakasimba

● Kugoverwa kwekumanikidzwa kwakafanana

 Zvikamu zveKutarisira Kupisa

● Kutamisa kupisa zvinobudirira

● Kuderera kwekupisa

 Masisitimu Ekusefa & Kupararira

● Kuchenesa gasi

● Nzvimbo dzinodzorwa dzekupararira

Graphite ine tumaburi (Porous Graphite) vs Graphite ine tumaburi (Dense Graphite)

Mhedziso: Graphite ine maburi inobvumira kudzora maitiro akarurama ayo graphite yakakora isingagoni kuwanikwa.

Nzira Yokusarudza Sei Graphite Yakakodzera Ine Maburi?

 Zviyero zvikuru zvekuongorora:

● Saizi yePore (μm level) → inokanganisa kupararira kwegasi

● Kupinda kwemvura (m²) → kunoratidza kushanda zvakanaka kwemvura

● Kuchena (ppm level) → kunokanganisa njodzi yekusvibiswa

● Kutenderera kwekupisa (W/m·K) → kunokanganisa kudzora tembiricha

● Kuenderana kwekuvhara (SiC, TaC)

Kusarudza kwakakodzera kunogona kuvandudza goho, kufanana, uye kugadzikana kwemaitiro.

Matambudziko uye Maitiro Eindasitiri

Kunyange zvazvo graphite ine maburi ichipa zvakanakira zvakajeka, matambudziko anosanganisira:

● Maitiro akaomarara ekugadzira

● Mutengo wakakwira uchienzaniswa negirafiti yakajairwa

Zvisinei, zvichikonzerwa nemidziyo yeSiC yemagetsi uye masisitimu esimba rinogona kushandiswazve, kudiwa kuri kuramba kuchikura.

Sekureva kweInternational Energy Agency, zvinhu zvepamusoro zvichave zvakakosha pakuvaka zvivakwa zvesimba zvechizvarwa chinotevera.

Mibvunzo Inowanzo bvunzwa

Mubvunzo 1: Chii chinoshandiswa negirafiti ine maburi?

Graphite ine maburi inoshandiswa mumabasa e semiconductor akadai seCVD, epitaxy, uye crystal growth kuti gasi ripararire uye ridzore kupisa.

Mubvunzo wechipiri: Nei girafiti ine maburi ichikosha muma semiconductors?

Inoita kuti gasi rifambe zvakanaka, rigare zvakanaka pakupisa kwakanyanya, uye ridzore kusvibiswa.

Mubvunzo 3: Ndezvipi zvinhu zvakakosha zve graphite ine porous?

Zvikamu zvakakosha zvinosanganisira porosity (10–30%), permeability (10⁻¹²–10⁻¹⁴ m²), thermal conductivity (80–150 W/m·K), uye kuchena (<50 ppm).
