Ge Crystal

"Ge crystal" kazhinji inoreva kristaro yakagadzirwa kubva kune element germanium (Ge), inova semiconductor zvinhu. Germanium inowanzoshandiswa mumunda we infrared optics uye photonics nekuda kwezvimiro zvayo zvakasiyana.

Heano mamwe akakosha makristasi egermanium uye mashandisiro awo:

1. Infrared Windows uye Lenzi: Germanium inoonekera munzvimbo ye infrared ye electromagnetic spectrum, kunyanya pakati pemafungu uye marefu-wave infrared ranges. Ichi chivakwa chinoita kuti ive yakakodzera kugadzira mahwindo uye lenzi anoshandiswa mune anopisa ekufungidzira masisitimu, infrared makamera, uye zvimwe zvigadzirwa zvemaziso zvinoshanda muinfrared wavelengths.
2. Detectors: Germanium inoshandiswawo se substrate yekugadzira infrared detectors, zvakadai se photodiodes uye photoconductors. Aya madetector anogona kushandura infrared radiation kuita chiratidzo chemagetsi, ichigonesa kuona uye kuyerwa kwechiedza che infrared.
3. Spectroscopy: Germanium makristasi anoshandiswa mu infrared spectroscopy zviridzwa. Anogona kushandiswa semabeamsplitters, prisms, uye windows kushandura uye kuongorora infrared mwenje wemakemikari uye zvinhu kuongorora.
4. Laser Optics: Germanium inogona kushandiswa sechinhu chemaziso mune mamwe infrared lasers, kunyanya iyo inoshanda mukati me-infrared range. Inogona kushandiswa senge yekuwana svikiro kana sechikamu mune laser cavities.
5. Space uye Astronomy: Makristasi eGermany anoshandiswa mune infrared telescopes uye nzvimbo-based observatories yekudzidza zvinhu zvemudenga zvinoburitsa infrared radiation. Vanobatsira vatsvakurudzi kuunganidza mashoko anokosha ane chokuita nechadenga asingaoneki muchiedza chinooneka.

Makristasi eGermania anogona kurimwa pachishandiswa nzira dzakasiyana siyana, senge nzira yeCzochralski (CZ) kana iyo Float Zone (FZ) nzira. Aya maitiro anosanganisira kunyunguduka uye kuomesa germanium nenzira inodzorwa kuti iumbe makristasi mamwe ane chaiwo zvivakwa.

Zvakakosha kuziva kuti nepo germanium iine yakasarudzika zvivakwa zve infrared optics, kushandiswa kwayo kunoganhurwa nezvinhu zvakaita semutengo, kuwanikwa, uye kutetepa kwayo kutapurirana zvichienzaniswa nezvimwe zvinhu zve infrared se zinc selenide (ZnSe) kana zinc sulfide (ZnS) . Kusarudzwa kwezvinhu kunoenderana neiyo chaiyo yekushandisa uye zvinodiwa zve optical system.
