Mhedzisiro yazvino yetsvagiridzo ye organic photodetectors

Vatsvagiri vakagadzira uye vakaratidza mwenje mutsva wegirinhi unotora pachena organic photodetectors ayo ane hanya zvakanyanya uye anoenderana neCMOS nzira dzekugadzira. Kubatanidza aya mafotodetectors matsva musilicone hybrid image sensors kunogona kubatsira kune akawanda maapplication. Aya maapplication anosanganisira light-based heart rate monitoring, kucherechedzwa kweminwe uye zvishandiso zvinoona kuvepo kwezvinhu zviri pedyo.

Ingave ichishandiswa mumafoni efoni kana esainzi makamera, mazhinji ekufungidzira ma sensors nhasi akavakirwa paCMOS tekinoroji uye inorganic photodetectors inoshandura masaini masaini kuita masaini emagetsi. Kunyangwe mafotodetectors akagadzirwa neorganic zvinhu ari kukwezva kutarisisa nekuti anogona kubatsira kuvandudza kunzwisiswa, kusvika parizvino zvaratidza kunetsa kugadzira yakakwirira-performance organic photodetectors.

Co-lead muongorori Sungjun Park, kubva kuAjou University kuSouth Korea, akati: "Kuisa organic photodetectors mune anogadzirwa neCMOS image sensors kunoda maorganic light absorbers ari nyore kugadzira pamwero mukuru uye anokwanisa kucherechedzwa nemifananidzo kugadzira mifananidzo yakapinza murima.

Vatsvagiri vanotsanangura iyo nyowani organic photodetector mujenari Optica. Ivo zvakare vakagadzira iyo yakasanganiswa RGB yekufungidzira sensor nekusimudzira yakajeka yegirini inonwisa organic photodetector pane silicon photodiode ine tsvuku uye bhuruu mafirita.

Kyung-Bae Park, mutungamiri weboka rekutsvagisa kubva kuSamsung Advanced Institute of Technology (SAIT) muSouth Korea, akati: “Nekuda kwekuunzwa kwehybrid organic buffer layer, green-selective light-absorbing organic layer inoshandiswa mune aya masensor emifananidzo inoderedza zvakanyanya kusangana pakati pemapikisi emavara akasiyana, uye dhizaini nyowani iyi inogona kugadzira mafoto makuru uye ekufungidzira. zvakasiyana-siyana zvekushandisa."

Zvimwe zvinoshanda organic photodetectors

Mazhinji organic zvinhu hazvina kukodzera kugadzirwa kwakawanda nekuda kwekunzwa kwavo kune tembiricha. Ivo vangave havakwanise kumirisana nekupisa kwakanyanya kunoshandiswa mushure mekurapa kana kuve isina kugadzikana kana ichishandiswa pamhepo tembiricha kwenguva yakareba. Kukunda dambudziko iri, masayendisiti akatarisana nekugadzirisa iyo buffer layer yephotodetector kuti ivandudze kugadzikana, kushanda nesimba, uye kuona. Detectability chiyero chekuti sei sensor inogona kuona isina simba masaini. "Takaunza tambo yekugezesa yemhangura (BCP): C60 hybrid buffer layer seye electron transport layer, iyo inopa organic photodetector yakakosha zvivakwa, zvinosanganisira kugona kwepamusoro uye kuderera kwakanyanya kwakasviba, izvo zvinoderedza ruzha," inodaro Sungjun Park. Iyo photodetector inogona kuiswa pasilicon photodiode ine tsvuku uye yebhuruu mafirita kugadzira iyo yakasanganiswa mufananidzo sensor.

Vatsvagiri vanoratidza kuti iyo nyowani photodetector inoratidza mareti ekuona anofananidzwa neaya akajairwa silicon photodiodes. Iyo detector yakashanda zvakatsiga kwemaawa maviri patembiricha iri pamusoro pe150 °C uye yakaratidza kugadzikana kwekushanda kwenguva refu kwemazuva makumi matatu pa85 °C. Aya mafotodetectors anoratidzawo kuita kwakanaka kwemavara.

Tevere, ivo vanoronga kugadzirisa nyowani mafotodetectors uye mahybrid image sensors kune akasiyana maapplication, senge nharembozha uye inopfekwa sensors (kusanganisira CMOS mifananidzo ma sensors), ma sensors epedyo, uye zvigunwe zvemunwe pazviratidziro.
