Sesivele senze lonke uchungechunge lwezithombe ezincane zokuvakasha ku-Habré. Kuboniswe wethu ,abuke elabhorethri yamarobhothi futhi wabheka isihloko sethu .
Namuhla sizokutshela ukuthi yini (futhi ini) enye yelabhorethri yethu ku-International Scientific Center for Functional Materials and Optoelectronics Devices esebenza kuyo.
Esithombeni: I-X-ray diffractometer DRON-8
Benzani lapha?
Ilabhorethri “Advanced Nanomaterials and Optoelectronic Devices” yavulwa ngesisekelo se-International Scientific Center, esebenza izinto ezintsha, okufaka phakathi ama-semiconductors, izinsimbi, ama-oxide asesimweni se-nanostructured, ngenjongo yokusebenzisa kumadivayisi we-optoelectronic namadivayisi.
Abafundi, abafundi abaneziqu kanye nabasebenzi baselabhorethri izakhiwo ze-nanostructures futhi udale amadivayisi amasha we-semiconductor we-micro- kanye ne-optoelectronics. Intuthuko isetshenziswa emkhakheni wokukhanyisa kwe-LED ukonga amandla futhi izodingeka esikhathini esizayo esiseduze kuma-electronic-voltage aphezulu kumagridi ahlakaniphile ().
Emphakathini wabafundi, indawo yocwaningo ekuLomonosov Street, isakhiwo 9 sibizwa ngokuthi “Ilabhorethri kaRomanov", njengoba kokubili iLabhorethri kanye neSikhungo ziholwa ngu- - , Udokotela Wesayensi Yemvelo Nezibalo, uprofesa oholayo kanye nomphathi we-Faculty of Laser Photonics and Optoelectronics e-ITMO University, umbhali wezincwadi zesayensi ezingaphezu kwamakhulu amathathu futhi owine izibonelelo nemiklomelo yesayensi yamazwe ngamazwe.
Izinsiza
Ilabhorethri ine-X-ray diffractometer DRON-8 evela enkampanini yaseRussia i-Burevestnik (ngenhla ku-KDPV). Lokhu kungenye yezinsimbi eziyinhloko zokuhlaziya izinto.
Isiza ukuveza ikhwalithi yamakristalu angumphumela nama-heterostructures ngokulinganisa i-X-ray diffraction spectra. Ukwelashwa okushisayo kwezakhiwo ze-semiconductor yefilimu emincane eyakhiwayo, sisebenzisa lokhu kufakwa kwasekhaya.
Sisebenzisa amasistimu okuhlola wezinga eliphezulu ukuze sibonise, siguqule futhi sihlele ama-LED. Ake sikhulume ngeyokuqala (esithombeni esingezansi kwesokunxele).
Lesi isiwashi esinembayo . Kuyisistimu ezenzakalelayo yokukhipha uketshezi lwe-viscous. I-dispenser enjalo ibalulekile ekusebenziseni ngokunembile okokusebenza kwe-phosphor ku-chip ye-LED ukuze kuzuzwe umbala okhanyayo owufunayo.
Ekuqaleni (ngokuzenzakalelayo), ama-LED amhlophe esiwajwayele asekelwe kuma-chips aphuma ebangeni eliluhlaza okwesibhakabhaka le-spectrum ebonakalayo yemisebe kazibuthe.
Le divayisi (esithombeni esivamile esiphakathi) ikala izici zamanje ze-voltage kanye ne-spectral yama-chips e-LED futhi igcina idatha elinganisiwe ngenani elikhulu lama-chip kumemori yekhompyutha. Kudingeka ukuhlola amapharamitha kagesi nawe-optical wamasampuli akhiqiziwe. Yile ndlela ukufakwa kubukeka ngayo uma uvula iminyango eluhlaza okwesibhakabhaka:
Idivayisi yesithathu esithombeni esijwayelekile iwuhlelo lokuhlunga nokulungiselela ama-LED ukuze afakwe ngokulandelayo. Ngokusekelwe ezicini ezilinganisiwe, uhlanganisa ipasipoti ye-LED. Isihlungi sibe sesisinika esinye sezigaba ezingama-256 kuye ngekhwalithi yedivayisi ye-semiconductor (isigaba 1 singama-LED angakhanyi, isigaba 256 yileso akhanya ngokugqama kakhulu ebangeni le-spectral elinikeziwe).
Esikhungweni sethu socwaningo samazwe ngamazwe sisebenza futhi ekukhuleni kwezinto zokwakha ze-semiconductor kanye ne-heterostructures. Ama-Heterostructures akhuliswa kusetshenziswa i-epitaxy ye-molecular beam ekufakweni kwe-RIBER MBE 49 enkampanini yozakwethu i-Connector-Optics.
Ukuthola amakristalu e-oxide eyodwa (okungama-semiconductors anegebe elibanzi) ekuncibilikeni, sisebenzisa ukufakwa kokukhula okusebenzayo okukhiqizwa ekhaya kwe-NIKA-3. Ama-semiconductors anegebe elibanzi angase abe nezinhlelo zokusebenza kuma-relays wamandla wesikhathi esizayo, amalaser e-VCSEL aqondile asebenza kahle kakhulu, izitholi ze-ultraviolet, njll.
Amaphrojekthi
Ezizindeni ze-International Scientific Center, ilabhorethri yethu yenza ucwaningo oluningi oluyisisekelo nolusetshenziswayo.
Isibonelo, kanye nabacwaningi abavela e-Ufa State Aviation Technical University, thina ama-conductor amasha ensimbi ane-conductivity eyengeziwe namandla aphezulu. Ukuzidala, kusetshenziswa izindlela ze-deformation eqinile yepulasitiki. Isakhiwo esihle se-alloy singaphansi kokwelashwa okushisa, okusabalalisa kabusha ukugxila kwama-athomu okungcola kundaba. Ngenxa yalokho, imingcele ye-conductivity nezici zamandla zezinto ziyathuthukiswa.
Izisebenzi zaselabhorethri zithuthukisa nobuchwepheshe bokukhiqiza ama-optoelectronic transceivers kusetshenziswa amasekethe ahlanganisiwe we-photonic. Ama-transceivers anjalo azothola ukusetshenziswa embonini yokudala amasistimu okudlulisa/okwamukela ulwazi olusebenza kahle kakhulu. Namuhla, isethi yemiyalo isivele ilungiselelwe ukwenziwa kwama-prototypes emithombo ye-radiation kanye nama-photodetectors. Imibhalo yokuklama yokuhlolwa kwabo nayo isilungisiwe.
Iphrojekthi yaselabhorethri ebalulekile ukwakhiwa kwezinto ezisetshenziswayo ze-semiconductor enegebe elibanzi nama-nanostructures anesici esiphansi sokuminyana. Ngokuzayo, sisebenzisa izinto ezisathuthukiswayo, sizokwazi ukukhiqiza amadivaysi e-semiconductor angakabi nawo ama-analogue emakethe.
Ochwepheshe bethu sebevele sebenayo Ama-LED, angashintsha amalambu e-ultraviolet asuselwa kumercury angaphephile. Inani lamadivayisi akhiqizwayo liseqinisweni lokuthi amandla emihlangano yethu ye-ultraviolet LED aphakeme izikhathi eziningana kunamandla ama-LED ngamanye - 25 W uma kuqhathaniswa no-3 W. Esikhathini esizayo, ubuchwepheshe buzothola ukusetshenziswa ekunakekelweni kwezempilo, ukwelashwa kwamanzi nakwezinye izindawo lapho kusetshenziswa imisebe ye-ultraviolet.
Iqembu lososayensi abavela ku-International Scientific Center yethu ukuthi amadivaysi e-optoelectronic esikhathi esizayo azosebenzisa izakhiwo eziphawulekayo zezinto ezinosayizi we-nano - amachashazi we-quantum, anemingcele ekhethekile ye-optical. Phakathi kwazo - noma ukukhanya okungashisi okushisayo kwento, okusetshenziswa komabonakude, omakhalekhukhwini kanye namanye amagajethi anezibonisi.
Sesivele ukwakhiwa kwemishini efanayo ye-optoelectronic yesizukulwane esisha. Kodwa ngaphambi kokuthi amagajethi angene emakethe, kufanele sisebenzise ubuchwepheshe bokukhiqiza izinto zokwakha futhi siqinisekise ukuphepha kwezinto ezisetshenziswayo ezitholakalayo kubasebenzisi.
Okunye ukuvakasha kwezithombe kumalabhorethri ethu:
