Kapangidwe ka ISAS Photodtector

Kapangidwe kaIngas Photodtector

Kuyambira m'ma 1980s, ofufuza kunyumba ndi akunja aphunzira kapangidwe ka ISAs Photoders, omwe amagawidwa m'mitundu itatu. Ndi Memiconductor-Semiconductor-MenCodertector (MSM-PD), ing Pali zosiyana zazikulu mu nsalu ndi mtengo wa iasis zithunzi zokhala ndi zida zosiyanasiyana, ndipo palinso kusiyana kwakukulu pakuchita ndi chipangizo.

Menaas Meas-Semiconductor-Satichithunzi, omwe akuwonetsedwa pa Chithunzi (a), ndi mawonekedwe apadera otengera ku Scottky Junction. Mu 1992, shi et al. anagwiritsa ntchito mankhwala ocheperako okhazikika a Etar Epitaxy (LP-CompPe) kuti akule zigawo za Epitaxy ndi okonzeka kwambiri pa 1.42 v. v. Gwiritsani ntchito gasi ma shalecular Broam Phitaxy (GSMBE) kuti akule Inalas-Inas-Inp Epitaxy wosanjikiza. Ma sulas osanjikiza atakhala ndi mikhalidwe yayitali, ndipo mikhalidwe yokulira idakonzedwa ndi miyeso yosiyanasiyana ya X-ray, kotero kuti chilankhulo cha Longtice chimakhala pakati pa 1 × 10⁻³. Izi zimapangitsa kuti pakhale magwiridwe antchito omwe ali ndi vuto lakuda lomwe lili pansi pa 0,75 Pa / v ndikusavuta.

Mphepo ya isas pini imayika mawonekedwe a p-lembani lolumikizirana ndi n-mtundu wolumikizirana, monga momwe muliri wambiri. Mu 2007, a.Poczezek et al. Zogwiritsidwa ntchito mumbela kuti zitheke kupukutira kwa buffer wotsika kuti musinthe mawonekedwe ndikugonjetsa vuto la malatiki pakati pa si ndi inp. Mocvd adagwiritsidwa ntchito kuphatikiza ma pini pinki pa inf gawo la inp, ndipo kuyanjana kwa chipangizocho kunali pafupifupi 0,57a / w. Mu 2011, labotale yankhondo (alr) adagwiritsa ntchito zithunzi zojambulajambula kuti mufufuze, zopingasa zotsika mtengo wa microwave quise ya ingnodtect. Pamaziko awa, mu 2012, alr anagwiritsa ntchito kafukufukuyu kwa maloboti, ndi zonyansa za zoposa 50 m ndi chosinthika cha 256 × 128.

The ISAASChithunzithunzi cha Avalchendi mtundu wa chithunzi ndi phindu, kapangidwe kake komwe kamasonyezedwa ku chithunzi (c). Inter electron-Hole Bat imapeza mphamvu zokwanira kudera lamagetsi mkati mwa dera lomwe limapezeka kudera la anthu akutali, kuti atulutse ma elekitikisi atsopano - amapanga zonyamula zosafanana, ndikupanga zonyamula zosafanana mu zinthu. Mu 2013, a George m chibes wofanana ndi Inaas ndi Atalas amawulutsa matenda a iloy, ndikuyika mphamvu yopanda ma elecroshuck ndikuchepetsa howo ya elemation. Pamalo ofanana ndi chizindikiro, Apd amawonetsa phokoso laling'ono komanso lamanzere lamakono. Mu 2016, dzuwa Jianfeng et al. Mangani 1570 nm laser yoyesera yoyeserera yoyeserera potengera chithunzi cha ingrasche avalche. Gawo lamkati laPhotodtectoradalandira zopereka komanso zotulutsa zachinsinsi, ndikupanga chida chonsecho. Zotsatira zoyesera zikuwonetsedwa mkuyu. (d) ndipo (e). Chithunzi (D) ndi chithunzi cha mbolo zoyerekeza, ndipo chithunzi (e) ndi chithunzi cha mitambo itatu. Zitha kuwona bwino kuti pawindo la madera c ili ndi mtunda wina ndi dera la a ndi b. Pulatifomu imazindikira zotsamira zosakwana 10 NS, mphamvu imodzi yokha imasinthika (1 ~ 3) MJ ya LJ Chifukwa cha phindu la apd

Pafupifupi, ndi kukula kwaukadaulo kuzengereza kunyumba ndi kunja, titha kugwiritsa ntchito molvd, Lucvd, matekinolojekiti ena kukonzekera ukadaulo waukulu wa epaas epitaxial gawo la infi. Ingas Photodtetors akuwonetsa kuti ali ndi vuto lakuda laposachedwa komanso lalitali kwambiri kuposa 0.75 Pa / ·MM ²²²²²poni pazachiwiri ndi 0,57. Kukula Kwamtsogolo kwa ISAS Photodesheni pazinthu ziwiri izi: Pakadali pano, zida zambiri za microelectronic pamsika ndizokhazikika, ndipo zomwe zidaphatikizapo zomwe ananazi ndi zikuluzikulu ndizomwe zimachitika. Kuthana ndi Mavuto monga latice Mummtch ndi matenthedwe ochulukirapo kusiyana ndi kofunikira pakuphunzira kwa ISAAS / SI; . Ndi kuwonjezeka kwa zigawo zikuluzikulu, chitoliro cha Lattice kudutsa inf gawo lapansi ndi zofooka, motero ndikofunikira kukonza chilema, ndikuchepetsa chipangizocho, ndikuchepetsa chipangizocho chakuda.
