InGaAs epitaxial wafer substrate PD Array photodetector arrays e ka sebelisoa bakeng sa LiDAR

Tlhaloso e Khutšoanyane:

InGaAs filimi ea epitaxial e bua ka indium gallium arsenic (InGaAs) filimi e le 'ngoe e tšesaane ea kristale e entsoeng ke theknoloji ea kgolo ea epitaxial holim'a substrate e itseng. Li-substrates tse tloaelehileng tsa InGaAs epitaxial ke indium phosphide (InP) le gallium arsenide (GaAs). Lisebelisoa tsena tsa substrate li na le boleng bo botle ba kristale le botsitso ba mocheso, tse ka fanang ka substrate e babatsehang bakeng sa kholo ea InGaAs epitaxial layers.
PD Array (Photodetector Array) ke letoto la li-photodetector tse ngata tse khonang ho lemoha matšoao a mangata a mahlo ka nako e le 'ngoe. Letlapa la epitaxial le hōlileng ho tloha ho MOCVD le sebelisoa haholo-holo ho li-diodes tsa photodetection, lesela la ho monya le entsoe ka U-InGaAs, doping e ka morao ke <5E14, 'me Zn e fapaneng e ka phethoa ke moreki kapa Epihouse. Matlapa a epitaxial a ile a hlahlojoa ke litekanyo tsa PL, XRD le ECV.

Likarolo tsa bohlokoa tsa leqephe la InGaAs laser epitaxial li kenyelletsa

1. Ho tšoana le Lattice: Ho lumellana hantle ha lattice ho ka finyelloa pakeng tsa InGaAs epitaxial layer le InP kapa GaAs substrate, kahoo ho fokotsa sekoli se nang le bokooa ba epitaxial layer le ho ntlafatsa tshebetso ea sesebelisoa.
2. Lekhalo le feto-fetohang la lihlopha: Lekhalo la lihlopha tsa thepa ea InGaAs le ka finyelloa ka ho fetola karolo ea likarolo tsa In le Ga, e leng se etsang hore InGaAs epitaxial sheet e be le menyetla e mengata ea tšebeliso ea lisebelisoa tsa optoelectronic.
3. High photosensitivity: InGaAs filimi ea epitaxial e na le kutloisiso e phahameng ea leseli, e leng se etsang hore e be tšimong ea ho lemoha photoelectric, puisano ea optical le melemo e meng e ikhethang.
4. Botsitso bo phahameng ba mocheso: InGaAs / InP epitaxial mohaho o na le botsitso bo botle ba mocheso o phahameng, 'me o ka boloka ts'ebetso e tsitsitseng ea lisebelisoa ka mocheso o phahameng.

Lisebelisoa tse ka sehloohong tsa matlapa a laser epitaxial a InGaAs a kenyelletsa

1. Lisebelisoa tsa Optoelectronic: Matlapa a epitaxial a InGaAs a ka sebelisoa ho etsa li-photodiode, li-photodetectors le lisebelisoa tse ling tsa optoelectronic, tse nang le mefuta e mengata ea likopo tsa puisano ea optical, pono ea bosiu le masimo a mang.

2. Lasers: Lipampiri tsa epitaxial tsa InGaAs li ka boela tsa sebelisoa ho etsa li-lasers, haholo-holo li-lasers tsa nako e telele, tse phethang karolo ea bohlokoa ho optical fiber communications, ts'ebetso ea indasteri le masimo a mang.

3. Lisele tsa letsatsi: InGaAs thepa e na le mefuta e mengata ea ho fetola lekhalo la lihlopha, tse ka finyellang litlhoko tsa lekhalo la lihlopha tse hlokoang ke lisele tse futhumatsang tsa photovoltaic, kahoo InGaAs epitaxial sheet e boetse e na le bokhoni bo itseng ba kopo tšimong ea lisele tsa letsatsi.

4. Litšoantšo tsa bongaka: Lisebelisoa tsa litšoantšo tsa bongaka (tse kang CT, MRI, joalo-joalo), bakeng sa ho lemoha le ho etsa litšoantšo.

5. Marang-rang a li-sensor: ho hlahloba tikoloho le ho lemoha khase, li-parameter tse ngata li ka hlahlojoa ka nako e le 'ngoe.

6. Boiketsetso ba indasteri: bo sebelisitsoeng mekhoeng ea pono ea mochini ho shebella boemo le boleng ba lintho moleng oa tlhahiso.

Nakong e tlang, thepa ea thepa ea InGaAs epitaxial substrate e tla tsoela pele ho ntlafala, ho kenyelletsa le ntlafatso ea katleho ea phetoho ea photoelectric le ho fokotsa maemo a lerata. Sena se tla etsa hore InGaAs epitaxial substrate e sebelisoe haholo lisebelisoa tsa optoelectronic, mme ts'ebetso e ntle haholo. Ka nako e ts'oanang, ts'ebetso ea ho lokisa e tla ntlafatsoa ka ho tsoelang pele ho fokotsa litšenyehelo le ho ntlafatsa ts'ebetso, e le ho finyella litlhoko tsa 'maraka o moholoanyane.

Ka kakaretso, InGaAs epitaxial substrate e na le boemo ba bohlokoa tšimong ea thepa ea semiconductor e nang le litšobotsi tse ikhethang le tebello e pharaletseng ea kopo.

XKH e fana ka litlhophiso tsa maqephe a epitaxial a InGaAs a nang le meaho le botenya bo fapaneng, a koahelang mefuta e mengata ea lits'ebetso tsa lisebelisoa tsa optoelectronic, lasers, le lisele tsa letsatsi. Lihlahisoa tsa XKH li entsoe ka lisebelisoa tse tsoetseng pele tsa MOCVD ho netefatsa ts'ebetso e phahameng le ho tšepahala. Mabapi le lisebelisoa, XKH e na le mekhoa e mengata ea mehloli ea machaba, e khonang ho sebetsana le palo ea litaelo, 'me e fane ka litšebeletso tsa bohlokoa tse kang ho ntlafatsa le ho arola. Mekhoa e metle ea ho fana ka thepa e netefatsa ho fana ka nako le ho finyella litlhoko tsa bareki bakeng sa boleng le linako tsa ho fana ka thepa.
