Sapphire Substrate
Tsanangudzo
Sapphire (Al2O3) single crystal yakanakisa multifunctional zvinhu.Iyo ine yakakwirira tembiricha kuramba, yakanaka kupisa conduction, kuomarara kwakanyanya, infrared transmission uye yakanaka kugadzikana kwemakemikari.Inoshandiswa zvakanyanya mundima dzakawanda dzeindasitiri, dziviriro yenyika uye tsvakiridzo yesainzi (senge tembiricha yepamusoro infrared hwindo).Panguva imwecheteyo, iri zvakare rudzi rweanonyanya kushandiswa single crystal substrate zvinhu.Ndiyo yekutanga sarudzo substrate mune yazvino bhuruu, violet, chena mwenje-emitting diode (LED) uye yebhuruu laser (LD) indasitiri (gallium nitride firimu inoda kuve epitaxial pasafire substrate kutanga), uye zvakare yakakosha superconducting. firimu substrate.Pamusoro peiyo Y-system, La system uye mamwe epamusoro-tembiricha superconducting mafirimu, anogona zvakare kushandiswa kukura matsva anoshanda MgB2 (magnesium diboride) superconducting mafirimu (kazhinji iyo single-crystal substrate ichave yakasvibiswa nemakemikari panguva yekugadzirwa kweMgB2. mafirimu).

Sapphire Substrate Tsanangudzo
Sapphire substrate inoreva chinhu chakajeka checrystalline chakagadzirwa nekamwechete crystal aluminium oxide (Al2O3).Izwi rekuti "safire" rinowanzoshandiswa kurondedzera corundum gemstone siyana, iyo inowanzova yebhuruu muvara.Nekudaro, maererano neiyo substrates, safire inoreva kugadzirwa kwakakura, isina ruvara, yakakwirira-yakachena kristaro inoshandiswa mumhando dzakasiyana dzekushandisa.Heano mamwe mapoinzi akakosha nezvesapphire substrates:
1. Chimiro cheCrystal: Safire ine hexagonal crystal structure umo maatomu ealuminium nemaatomu eokisijeni zvinodzokororwa zvakarongeka.Iyo ndeye trigonal crystal system.
2. Kuoma kwepamusoro: Safiri ndeimwe yezvinhu zvakaoma zvikuru zvinozivikanwa, neMohs kuoma kwe 9. Izvi zvinoita kuti zvive zvakanyanya kukwenya uye abrasion kusagadzikana, zvichibatsira pakugara kwayo uye hupenyu hurefu mukushandiswa.
3. Chiedza chekufambisa: Safire ine chiedza chakanakisisa chekufambisa, kunyanya munzvimbo dzinoonekwa uye dziri pedyo-infrared.Inogona kufambisa mwenje kubva panosvika 180 nm kusvika 5500 nm, ichiita kuti ive yakakodzera kune dzakasiyana siyana dzemaziso uye optoelectronic application.
4. Thermal uye mechanical properties: Safiri ine yakanaka yekupisa uye mechanical properties, yakakwirira kunyunguduka, yakaderera thermal kuwedzera coefficient, uye yakanakisa thermal conductivity.Inogona kumira kutonhora kwepamusoro, kushushikana kwemagetsi uye kupisa bhasikoro, zvichiita kuti ive yakakodzera kupisa kwepamusoro uye kushandiswa kwemasimba makuru.
5. Kugadzikana kwemakemikari: Safiri ine kugadzikana kwemakemikari uye inogona kuramba yakawanda acids, alkali uye organic solvents.Ichi chimiro chinovimbisa kusimba uye kuvimbika munzvimbo dzakasiyana dzakaoma.
6. Magetsi ekudzivirira zvinhu: Safire inyanzvi yemagetsi insulator, iyo inobatsira kune zvikumbiro zvinoda kuparadzaniswa kwemagetsi kana kuvhara.
7. Kushandisa: Sapphire substrates inoshandiswa zvakanyanya mu optoelectronics, semiconductors, light-emitting diodes, laser diodes, optical windows, watch crystals uye tsvakurudzo yesayenzi.
Sapphire substrates inokosheswa zvakanyanya nekuda kwekusanganiswa kwayo kwemaziso, mechanical, thermal uye chemical properties.Hunhu hwayo hwakatanhamara hunoita kuti ive yakakodzera kune inoda maapplication inoda kusimba kwepamusoro, kujeka kwepamusoro kwemaziso, kuvharwa kwemagetsi uye kuramba kune zvakatipoteredza zvinhu.
