Isu takatoita nhevedzano yediki diki mafoto excursions paHabrΓ©. Kuratidzwa kwedu , akatarisa mune marobhoti murabhoritari uye akatarisa mune yedu thematic .
Nhasi tichakuudza kuti chii (uye chii) imwe yemarabhoritari edu kuInternational Sayenzi Center yeFunctional Materials uye Optoelectronics Devices iri kushanda pairi.
Mumufananidzo: X-ray diffractometer DRON-8
Vari kuitei pano?
Iyo laboratori "Advanced Nanomaterials uye Optoelectronic Devices" yakavhurwa pahwaro hweInternational Sayenzi Center, inobata zvinhu zvitsva, zvinosanganisira semiconductors, simbi, oxides mune nanostructured state, nechinangwa chekushandisa kwavo mune optoelectronic madivayiri nemidziyo.
Vadzidzi, vadzidzi vakapedza kudzidza uye vashandi verabhoritari zvivakwa zve nanostructures uye kugadzira mitsva semiconductor zvishandiso zvemicro- uye optoelectronics. Zviitiko izvi zvinoshandiswa mundima yemagetsi-inoshanda magetsi emwenje uye ichave iri kudiwa munguva pfupi iri kutevera mune yakakwira-voltage yemagetsi kune smart grids ().
Munharaunda yevadzidzi, saiti yekutsvagisa paLomonosov Street, kuvaka 9 inonzi "murabhoritari Romanov", sezvo vese Laboratory neCentre zvichitungamirwa ne- - , Chiremba wePhysical and Mathematical Sciences, purofesa anotungamira uye dhipatimendi weFaculty yeLaser Photonics uye Optoelectronics paITMO University, munyori wezvinyorwa zvesainzi zvinopfuura mazana matatu uye akahwina mari zhinji dzesainzi dzepasi rose nemibairo.
Zvigadzirwa
Iyo laboratori ine X-ray diffractometer DRON-8 kubva kuRussia kambani Burevestnik (pamusoro paKDPV). Ichi ndicho chimwe chezvishandiso zvikuru zvekuongorora zvinhu.
Inobatsira kuratidza kunaka kwemakristasi anoguma uye heterostructures nekuyera X-ray diffraction spectra. Nekupisa kwekupisa kweakaonda-firimu semiconductor zvimiro zviri kugadzirwa, isu tinoshandisa iyi yekumisikidza yekumba.
Isu tinoshandisa state-of-the-art pilot-scale masisitimu kuratidza, kugadzirisa uye kuronga maLED. Ngatitaure nezve yekutanga (inoratidzwa pazasi kuruboshwe).
Iyi ndiyo chaiyo dispenser . Iyo i automated system yekugovera viscous zvinwiwa. Yakadaro dispenser yakakosha pakushandisa nemazvo phosphor zvinhu kune LED chip kuitira kuti uwane yaunoda kupenya ruvara.
Pakutanga (nekudaro), iwo ma LED machena atinoziva akavakirwa pamachipisi anoburitsa mumhando yebhuruu yeanooneka spectrum emagetsi emagetsi.
Ichi chishandiso (mune mufananidzo wepakati) inoyera yazvino-voltage uye spectral maitiro e LED machipi uye inochengeta iyo yakayerwa data yehuwandu hukuru hwemachipi mundangariro yekombuta. Inodiwa kuti utarise magetsi uye optical parameters ezvigadzirwa zvakagadzirwa. Izvi ndizvo zvinoita kuisirwa kana iwe ukavhura magonhi ebhuruu:
Chishandiso chechitatu mumufananidzo wakajairwa isystem yekuronga nekugadzirira maLED ekuzotevera kuiswa. Zvichienderana neakayerwa maitiro, anounganidza pasipoti ye LED. Iyo inorongera inozopa kune imwe yezvikamu mazana maviri nemakumi mashanu nenhanhatu zvichienderana nemhando ye semiconductor mudziyo (chikamu 256 maLED asingapenye, chikamu 1 ndiwo anopenya zvakanyanya mune yakapihwa spectral renji).
PaInternational Research Center yedu tiri kushandawo pakukura kwesemiconductor zvinhu uye heterostructures. Heterostructures inokura uchishandisa molecular beam epitaxy pane RIBER MBE 49 yekumisikidza pakambani yemubatanidzwa Connector-Optics.
Kuti tiwane oxide imwe chete makristasi (ayo ari wide-gap semiconductors) kubva mukunyunguduka, isu tinoshandisa mudzimba inogadzirwa multifunctional kukura kuisirwa NIKA-3. Wide-gap semiconductors inogona kunge iine maapplication mune ramangwana relay relay, yakakwirira-inoshanda yakatwasuka VCSEL lasers, ultraviolet detectors, nezvimwe.
Zvirongwa
Panzvimbo dzeInternational Scientific Center, marabhoritari yedu inoita zvakasiyana-siyana zvakakosha uye zvekushandisa tsvakiridzo.
Somuenzaniso, pamwe chete nevatsvakurudzi vanobva kuUfa State Aviation Technical University, isu simbi itsva conductors ine yakawedzera conductivity uye yakakwirira simba. Kuzvigadzira, nzira dzekusimba dzepurasitiki deformation dzinoshandiswa. Iyo yakatsetseka-yakaomeswa chimiro cheiyo alloy inoiswa mukupisa kurapwa, iyo inogovera zvakare kuunganidzwa kwemaatomu ekusachena mune izvo zvinhu. Nekuda kweizvozvo, iyo conductivity parameters uye simba hunhu hwechinyorwa hunovandudzwa.
Vashandi veLabhoritari vari kugadzirawo matekinoroji ekugadzira optoelectronic transceivers vachishandisa photonic integrated circuits. Matransceivers akadaro achawana kushandiswa muindasitiri yekugadzira yakakwirira-yekuita ruzivo rwekufambisa / yekugamuchira masisitimu. Nhasi, seti yemirayiridzo yakatogadzirirwa kugadzirwa kweprototypes yeradiation sources uye photodetectors. Zvinyorwa zvekugadzira zvekuyedzwa kwavo zvakagadzirirwawo.
Yakakosha laboratori chirongwa kusikwa kweyakafara-gap semiconductor zvinhu uye nanostructures ine yakaderera defect density. Mune ramangwana, tichishandisa zvinhu zviri kugadzirwa, tichakwanisa kugadzira magetsi ekuchengetedza semiconductor zvishandiso izvo zvisati zvave nemaanalogues pamusika.
Nyanzvi dzedu dzatove nadzo LEDs, iyo inogona kutsiva isina kuchengeteka mercury-based ultraviolet marambi. Kukosha kwemidziyo yakagadzirwa iri muchokwadi chekuti simba reiyo ultraviolet LED maassemblies akakwira kakawanda kupfuura simba rema LEDs ega - 25 W versus 3 W. Mune ramangwana, tekinoroji ichawana kushandiswa mune hutano, kurapwa kwemvura uye dzimwe nzvimbo uko ultraviolet radiation inoshandiswa.
Boka revasayendisiti kubva kuInternational Sayenzi Center yedu kuti ramangwana optoelectronic zvishandiso zvichashandisa zvinoshamisa zvimiro zve nano-saizi zvinhu - quantum dots, ane akakosha optical paramita. Pakati pavo - kana kupenya kusina kupisa kwechinhu, chinoshandiswa mumaterevhizheni, mafoni uye mamwe majeti ane zviratidzo.
Isu tatova kusikwa kwezvakafanana optoelectronic madivayiri echizvarwa chitsva. Asi magajeti asati asvika pamusika, isu tinofanirwa kugadzira matekinoroji ekugadzira zvinhu uye nekusimbisa kuchengetedzwa kwezvinhu zvinokonzeresa zvevashandisi.
