Ka taea te whakamahi i ngā huinga whakaahua PD Array o te papa wafer epitaxial InGaAs mō te Whakaahua Matua o LiDAR.

Whakaahuatanga Poto:

Ko te kiriata epitaxial InGaAs e pā ana ki te rauemi kiriata angiangi kotahi-kiriata indium gallium arsenic (InGaAs) i hangaia mā te hangarau tipu epitaxial i runga i tētahi papa motuhake. Ko ngā papa epitaxial InGaAs e kitea whānuitia ana ko te indium phosphide (InP) me te gallium arsenide (GaAs). He pai te kounga tioata me te pumau o te wera o ēnei rauemi papa, ā, ka taea te whakarato i tētahi papa pai mō te tipu o ngā papa epitaxial InGaAs.
Ko te PD Array (Photodetector Array) he huinga o ngā photodetector maha e kaha ana ki te kite i ngā tohu whatu maha i te wā kotahi. Ko te pepa epitaxial i whakatupuria mai i te MOCVD e whakamahia ana i roto i ngā diode photodetection, ko te paparanga mimiti he mea tito mai i te U-InGaAs, ko te doping papamuri he <5E14, ā, ka taea te whakaoti i te Zn kua horapa e te kiritaki, e te Epihouse rānei. I tātarihia ngā papa epitaxial mā te ine PL, XRD me te ECV.

Tukua mai he īmēra ki a mātou

Ngā Āhuatanga

Ko ngā āhuatanga matua o te pepa epitaxial taiaho InGaAs ko:

1. Te whakataurite i te whatunga: Ka taea te whakatutuki i te whakataurite whatunga pai i waenga i te paparanga epitaxial InGaAs me te papa InP, GaAs rānei, mā te whakaiti i te kiato hapa o te paparanga epitaxial me te whakapai ake i te mahi a te taputapu.
2. Āputa roopu ka taea te whakarite: Ka taea te whakatutuki i te āputa roopu o te rauemi InGaAs mā te whakarerekē i te ōwehenga o ngā wāhanga In me Ga, ā, he whānuitia ngā tono mō te pepa epitaxial InGaAs i roto i ngā taputapu optoelectronic.
3. Teitei o te aro ki te mārama: He tino aro te kiriata epitaxial InGaAs ki te mārama, ā, he pai rawa atu tēnei i roto i te mara o te kimi hiko, te whakawhitiwhiti kōrero whatu me ētahi atu painga ahurei.
4. Te pumau o te pāmahana teitei: He tino pai te pumau o te hanganga epitaxial InGaAs/InP i te pāmahana teitei, ā, ka taea te pupuri i te mahi pumau o te taputapu i ngā pāmahana teitei.

Ko ngā whakamahinga matua o ngā papa epitaxial taiaho InGaAs ko

1. Ngā taputapu optoelectronic: Ka taea te whakamahi i ngā papa epitaxial InGaAs ki te hanga i ngā photodiode, ngā photodetector me ētahi atu taputapu optoelectronic, he whānuitia ngā tono i roto i te whakawhitiwhiti kōrero whatu, te tirohanga pō me ētahi atu mara.

2. Ngā Taiaho: Ka taea hoki te whakamahi i ngā rau epitaxial InGaAs hei hanga taiaho, inā koa ngā taiaho roa-ngaru, he mea nui ēnei i roto i ngā whakawhitiwhitinga muka whatu, te tukatuka ahumahi me ētahi atu mara.

3. Ngā pūtau pūngao rā: He whānui te awhe whakarerekētanga o te āputa roopu o te rauemi InGaAs, ka taea te whakatutuki i ngā whakaritenga āputa roopu e hiahiatia ana e ngā pūtau photovoltaic wera, nō reira he pūmanawa tono anō hoki tō te pepa epitaxial InGaAs i roto i te mara o ngā pūtau pūngao rā.

4. Whakaahua hauora: I roto i ngā taputapu whakaahua hauora (pēnei i te CT, MRI, me ētahi atu), hei kimi me te whakaahua.

5. Whatunga pūoko: i roto i te aroturukitanga taiao me te kimi hau, ka taea te aroturuki i ngā tawhā maha i te wā kotahi.

6. Aunoatanga ahumahi: e whakamahia ana i roto i ngā pūnaha tirohanga mīhini hei aroturuki i te mana me te kounga o ngā mea kei runga i te raina whakaputa.

I ngā rā kei te heke mai, ka haere tonu te whakapai ake i ngā āhuatanga rauemi o te papa epitaxial InGaAs, tae atu ki te whakapai ake i te whai huatanga o te whakawhiti hiko whakaahua me te whakaiti i ngā taumata haruru. Mā tēnei ka nui ake te whakamahinga o te papa epitaxial InGaAs i roto i ngā taputapu optoelectronic, ā, ka tino pai ake te mahi. I taua wā anō, ka arotau tonutia te tukanga whakarite hei whakaiti i ngā utu me te whakapai ake i te whai huatanga, kia tutuki ai ngā hiahia o te mākete whānui.

I te nuinga o te wā, he tūranga nui tō te papa epitaxial InGaAs i roto i te mara o ngā rauemi semiconductor nā ōna āhuatanga ahurei me ōna tūmanakohanga whānui mō te tono.

Ka tukuna e XKH ngā whakaritenga o ngā rau epitaxial InGaAs me ngā hanganga me ngā matotoru rerekē, e kapi ana i te whānuitanga o ngā tono mō ngā taputapu optoelectronic, ngā laser, me ngā pūtau solar. He taputapu MOCVD matatau ngā hua a XKH hei whakarite i te mahi teitei me te pono. Mō ngā mahi kawe, he whānuitanga o ngā hongere pūtake o te ao a XKH, ka taea te whakahaere ngāwari i te maha o ngā ota, me te whakarato ratonga uara-tāpiri pēnei i te whakapai ake me te wehewehe. Mā ngā tukanga tuku whai hua ka whakarite kia tukuna i te wā tika, ā, ka tutuki hoki ngā hiahia o te kiritaki mō te kounga me ngā wā tuku.
