InGaAs epitaxial wafer substrate PD Array photodetector arrays angagwiritsidwe ntchito pa LiDAR

Kufotokozera Kwachidule:

Kanema wa InGaAs epitaxial amatanthauza indium gallium arsenic (InGaAs) filimu imodzi yopyapyala yopangidwa ndi ukadaulo wa epitaxial kukula pagawo linalake. Magawo odziwika a InGaAs epitaxial ndi indium phosphide (InP) ndi gallium arsenide (GaAs). Zida zam'munsizi zili ndi khalidwe labwino la kristalo ndi kukhazikika kwa kutentha, zomwe zingapereke gawo labwino kwambiri la kukula kwa InGaAs epitaxial layers.
PD Array (Photodetector Array) ndi gulu la ma photodetector angapo omwe amatha kuzindikira ma siginecha angapo nthawi imodzi. Tsamba la epitaxial lomwe limakula kuchokera ku MOCVD limagwiritsidwa ntchito makamaka mu ma diode a photodetection, gawo loyamwa limapangidwa ndi U-InGaAs, doping yakumbuyo ndi <5E14, ndipo Zn yofalikira imatha kumalizidwa ndi kasitomala kapena Epihouse. Mapiritsi a epitaxial adawunikidwa ndi miyeso ya PL, XRD ndi ECV.

Zofunika kwambiri za InGaAs laser epitaxial sheet zikuphatikiza

1. Kufananiza kwa latisi: Kufananitsa kwabwino kwa latisi kumatha kupezedwa pakati pa InGaAs epitaxial layer ndi InP kapena GaAs gawo lapansi, potero kuchepetsa kuchuluka kwa chilema cha epitaxial layer ndikuwongolera magwiridwe antchito a chipangizocho.
2. Kusiyana kwa gulu losinthika: Kusiyana kwa gulu la zinthu za InGaAs kungapezeke mwa kusintha gawo la zigawo za In ndi Ga, zomwe zimapangitsa InGaAs epitaxial sheet kukhala ndi chiyembekezo chochuluka chogwiritsira ntchito zipangizo za optoelectronic.
3. High photosensitivity: InGaAs filimu ya epitaxial imakhala ndi mphamvu zambiri zowunikira kuwala, zomwe zimapangitsa kuti pakhale mawonekedwe a photoelectric, kuyankhulana kwa kuwala ndi ubwino wina wapadera.
4. Kukhazikika kwa kutentha kwapamwamba: InGaAs/InP epitaxial structure ili ndi kukhazikika kwapamwamba kwambiri kwa kutentha, ndipo imatha kusunga chipangizo chokhazikika pa kutentha kwakukulu.

Ntchito zazikulu za mapiritsi a InGaAs laser epitaxial zimaphatikizapo

1. Zida za Optoelectronic: Mapiritsi a epitaxial a InGaAs angagwiritsidwe ntchito popanga ma photodiodes, photodetectors ndi zipangizo zina za optoelectronic, zomwe zimakhala ndi ntchito zambiri pakuyankhulana kwa kuwala, masomphenya a usiku ndi zina.

2. Ma laser: Mapepala a epitaxial a InGaAs angagwiritsidwenso ntchito popanga ma lasers, makamaka ma laser atali-wavelength, omwe amagwira ntchito yofunika kwambiri pakulumikizana kwa fiber optical, processing mafakitale ndi zina.

3. Maselo a Dzuwa: InGaAs zakuthupi zimakhala ndi kusintha kwakukulu kwa kusiyana kwa bandi, zomwe zingathe kukwaniritsa zofunikira za bandi zomwe zimafunidwa ndi maselo otentha a photovoltaic, kotero InGaAs epitaxial pepala imakhalanso ndi mphamvu zina zogwiritsira ntchito m'munda wa maselo a dzuwa.

4. Kujambula kwachipatala: Muzojambula zachipatala (monga CT, MRI, etc.), kuti mudziwe ndi kujambula.

5. Sensor network: poyang'anira chilengedwe ndi kufufuza gasi, magawo angapo amatha kuyang'aniridwa nthawi imodzi.

6. Industrial automation: imagwiritsidwa ntchito mu makina owonera makina kuti aziyang'anira momwe zinthu zilili komanso mtundu wa zinthu zomwe zili pamzere wopanga.

M'tsogolomu, katundu wa InGaAs epitaxial substrate adzapitirizabe kusintha, kuphatikizapo kusintha kwa photoelectric kutembenuka bwino ndi kuchepetsa phokoso. Izi zipangitsa gawo la InGaAs epitaxial kuti ligwiritsidwe ntchito kwambiri pazida za optoelectronic, ndipo magwiridwe ake ndiabwino kwambiri. Panthawi imodzimodziyo, ndondomeko yokonzekera idzakonzedwanso mosalekeza kuti achepetse ndalama ndikuwongolera bwino, kuti akwaniritse zosowa za msika waukulu.

Nthawi zambiri, gawo lapansi la InGaAs epitaxial limakhala ndi malo ofunikira pazida za semiconductor zomwe zimakhala ndi mawonekedwe ake apadera komanso mwayi wogwiritsa ntchito kwambiri.

XKH imapereka makonda a InGaAs epitaxial sheets okhala ndi mapangidwe osiyanasiyana ndi makulidwe osiyanasiyana, kuphimba mitundu ingapo yamapulogalamu opangira zida za optoelectronic, ma lasers, ndi ma cell a solar. Zogulitsa za XKH zimapangidwa ndi zida zapamwamba za MOCVD kuti zitsimikizire kuti zikuyenda bwino komanso zodalirika. Pankhani ya mayendedwe, XKH ili ndi njira zambiri zapadziko lonse lapansi, zomwe zimatha kuthana ndi kuchuluka kwa madongosolo, ndikupereka mautumiki owonjezera monga kuwongolera ndi magawo. Njira zoperekera bwino zimatsimikizira kutumiza pa nthawi yake ndikukwaniritsa zofunikira zamakasitomala pazabwino komanso nthawi yobweretsera.
