Peb twb tau ua tag nrho cov duab me me mus ncig ua si ntawm Habré. Qhia peb , saib nyob rau hauv lub robotics lab thiab ntsia rau hauv peb thematic .
Niaj hnub no peb yuav qhia koj txog dab tsi (thiab dab tsi) ib qho ntawm peb lub chaw soj nstuam ntawm International Scientific Center for Functional Materials thiab Optoelectronics Devices tab tom ua haujlwm.
Hauv daim duab: X-ray diffractometer DRON-8
Lawv ua dab tsi ntawm no?
Lub chaw soj nstuam "Advanced Nanomaterials thiab Optoelectronic Devices" tau qhib los ntawm International Scientific Center, uas cuam tshuam nrog cov ntaub ntawv tshiab, suav nrog semiconductors, hlau, oxides nyob rau hauv lub xeev nanostructured, rau lub hom phiaj ntawm lawv siv nyob rau hauv optoelectronic pab kiag li lawm thiab pab kiag li lawm.
Cov tub ntxhais kawm, cov tub ntxhais kawm tiav thiab cov neeg ua haujlwm hauv chav kuaj cov khoom ntawm nanostructures thiab tsim cov khoom siv semiconductor tshiab rau micro- thiab optoelectronics. Cov kev txhim kho yog siv nyob rau hauv lub tshav pob ntawm lub zog-npaum LED teeb pom kev zoo thiab yuav xav tau nyob rau hauv lub neej yav tom ntej nyob rau hauv lub high-voltage electronics rau ntse daim phiaj ().
Hauv zej zog cov tub ntxhais kawm, qhov chaw tshawb fawb ntawm Lomonosov Street, lub tsev 9 hu ua "Romanov's lab", txij li ob lub Laboratory thiab Center yog coj los ntawm - , Tus kws kho mob ntawm Physical and Mathematical Sciences, tus thawj xibfwb thiab tus thawj saib xyuas ntawm Kws qhia ntawv ntawm Laser Photonics thiab Optoelectronics ntawm ITMO University, tus sau ntau tshaj peb puas scientific cov ntawv tshaj tawm thiab yeej ntawm ntau qhov kev tshawb fawb thoob ntiaj teb thiab khoom plig.
Khoom siv
Lub chaw kuaj mob muaj X-ray diffractometer DRON-8 los ntawm Lavxias lub tuam txhab Burevestnik (saum toj no ntawm KDPV). Qhov no yog ib qho ntawm cov cuab yeej tseem ceeb rau kev txheeb xyuas cov ntaub ntawv.
Nws pab tus cwj pwm zoo ntawm qhov tshwm sim muaju thiab heterostructures los ntawm kev ntsuas X-ray diffraction spectra. Rau kev kho cua sov ntawm nyias-zaj duab xis semiconductor qauv tsim, peb siv qhov kev teeb tsa hauv tsev no.
Peb siv lub xeev-of-the-art pilot-scale systems los ua tus yam ntxwv, hloov kho thiab txheeb LEDs. Cia peb tham txog thawj tus (daim duab hauv qab no ntawm sab laug).
Qhov no yog ib tug precision dispenser . Nws yog ib qho automated system rau dispensing kua viscous. Xws li lub dispenser yog qhov tseem ceeb rau kev siv cov khoom siv phosphor kom raug rau LED nti kom ua tiav cov xim uas xav tau.
Thaum pib (los ntawm lub neej ntawd), cov LEDs dawb uas peb paub txog yog ua raws li cov chips uas tawm hauv cov xim xiav ntawm qhov pom ntawm cov hluav taws xob hluav taws xob hluav taws xob.
Cov cuab yeej no (hauv daim duab dav dav hauv qhov chaw) ntsuas qhov tam sim no-voltage thiab spectral yam ntxwv ntawm LED chips thiab khaws cov ntaub ntawv ntsuas rau ntau cov chips hauv computer nco. Nws yog tsim nyog los xyuas cov hluav taws xob thiab kho qhov muag tsis pom kev ntawm cov qauv tsim. Nov yog qhov kev teeb tsa zoo li yog tias koj qhib lub qhov rooj xiav:
Cov cuab yeej thib peb hauv daim duab dav dav yog lub kaw lus rau kev txheeb xyuas thiab npaj LEDs rau kev teeb tsa tom ntej. Raws li cov yam ntxwv ntsuas, nws suav nrog daim ntawv hla tebchaws rau LED. Tus sorter ces muab nws rau ib qho ntawm 256 pawg nyob ntawm qhov zoo ntawm cov khoom siv semiconductor (qib 1 yog cov LEDs tsis ci, qeb 256 yog cov uas ci ntsa iab tshaj plaws hauv qhov muab spectral ntau).
Ntawm peb Lub Chaw Tshawb Fawb Thoob Ntiaj Teb peb kuj tseem ua haujlwm ntawm kev loj hlob ntawm cov khoom siv semiconductor thiab heterostructures. Heterostructures tau loj hlob siv molecular beam epitaxy ntawm RIBER MBE 49 kev teeb tsa ntawm tus khub tuam txhab Connector-Optics.
Txhawm rau kom tau txais oxide ib leeg muaju (uas yog qhov sib txawv ntawm qhov sib txawv) los ntawm cov yaj, peb siv cov khoom siv hauv tsev ua ntau yam kev loj hlob NIKA-3. Wide-gap semiconductors tej zaum yuav muaj kev siv rau yav tom ntej fais fab relays, high-efficiency ntsug VCSEL lasers, ultraviolet detectors, thiab lwm yam.
Tej Hauj Lwm
Ntawm qhov chaw ntawm International Scientific Center, peb lub chaw soj nstuam ua ntau yam kev tshawb fawb thiab siv tau.
Piv txwv li, ua ke nrog cov kws tshawb fawb los ntawm Ufa State Aviation Technical University, peb tshiab hlau conductors nrog nce conductivity thiab siab zog. Txhawm rau tsim lawv, cov txheej txheem ntawm cov yas deformation khaus yog siv. Cov qauv nplua-grained ntawm cov hlau yog raug rau kev kho cua sov, uas rov faib cov concentration ntawm impurity atoms hauv cov khoom. Yog li ntawd, cov conductivity tsis thiab lub zog yam ntxwv ntawm cov khoom yog txhim kho.
Cov neeg ua haujlwm hauv chav kuaj tseem tab tom tsim cov thev naus laus zis rau kev tsim khoom siv hluav taws xob optoelectronic transceivers siv photonic integrated circuits. Xws li transceivers yuav pom daim ntawv thov hauv kev lag luam ntawm kev tsim cov ntaub ntawv xov xwm kev sib kis / txais cov tshuab. Niaj hnub no, ib txheej ntawm cov lus qhia twb tau npaj rau kev tsim cov qauv ntawm cov khoom siv hluav taws xob thiab photodetectors. Tsim cov ntaub ntawv rau lawv qhov kev sim kuj tau npaj.
Qhov haujlwm tseem ceeb hauv chav kuaj tsim cov khoom siv dav-gap semiconductor thiab nanostructures nrog qhov tsis xws luag. Nyob rau hauv lub neej yav tom ntej, siv cov ntaub ntawv tsim, peb yuav muaj peev xwm tsim lub zog-txuag semiconductor li uas tseem tsis tau muaj analogues nyob rau hauv kev ua lag luam.
Peb cov kws tshaj lij muaj lawm LEDs, uas tuaj yeem hloov cov teeb tsis zoo mercury-based ultraviolet. Tus nqi ntawm cov khoom tsim tau nyob rau hauv qhov tseeb tias lub zog ntawm peb cov khoom siv ultraviolet LED yog ob peb zaug siab dua lub zog ntawm ib tus neeg LEDs - 25 W piv rau 3 W. Yav tom ntej, thev naus laus zis yuav pom daim ntawv thov hauv kev kho mob, kev kho dej thiab lwm qhov chaw uas siv hluav taws xob ultraviolet.
Ib pawg kws tshawb fawb los ntawm peb lub International Scientific Center tias yav tom ntej optoelectronic li yuav siv cov khoom zoo kawg li ntawm nano-loj cov khoom - quantum dots, uas muaj qhov tshwj xeeb optical tsis. Ntawm lawv - los yog qhov tsis muaj cua sov ntawm ib qho khoom siv, uas yog siv hauv TV, smartphones thiab lwm yam khoom siv nrog cov khoom siv.
Peb twb kev tsim cov khoom siv optoelectronic zoo sib xws ntawm cov tiam tshiab. Tab sis ua ntej lub gadgets ntaus lub lag luam, peb yuav tsum tau ua hauj lwm tawm lub technologies los tsim cov ntaub ntawv thiab paub meej tias muaj kev ruaj ntseg ntawm cov khoom tshwm sim rau cov neeg siv.
