Tachita kale maulendo angapo ang'onoang'ono a zithunzi pa Habré. Kuwonetsa kwathu , anayang'ana mu labotale ya robotics ndikuyang'ana mutu wathu .
Lero tikuwuzani (ndi chiyani) imodzi mwa labotale yathu ku International Scientific Center for Functional Materials and Optoelectronics Devices ikugwira ntchito.
Pa chithunzi: X-ray diffractometer DRON-8
Kodi akutani pano?
Laborator "Advanced Nanomaterials and Optoelectronic Devices" idatsegulidwa pamaziko a International Scientific Center, yomwe imachita ndi zipangizo zatsopano, kuphatikizapo semiconductors, zitsulo, oxides mu dziko nanostructured, cholinga cha ntchito yawo optoelectronic zipangizo ndi zipangizo.
Ophunzira, ophunzira omaliza maphunziro ndi ogwira ntchito za labotale katundu wa nanostructures ndikupanga zida zatsopano za semiconductor zama micro- ndi optoelectronics. Zomwe zikuchitikazi zimagwiritsidwa ntchito pamagetsi opangira magetsi a LED ndipo zidzafunidwa posachedwapa mumagetsi apamwamba amagetsi amagetsi anzeru ().
Pagulu la ophunzira, malo ofufuzira pa Lomonosov Street, nyumba 9 amatchedwa "Laborator ya Romanov", popeza onse Laboratory ndi Center amatsogozedwa ndi - , Doctor of Physical and Mathematics Sciences, pulofesa wotsogolera ndi mkulu wa Faculty of Laser Photonics ndi Optoelectronics pa yunivesite ya ITMO, wolemba mabuku oposa mazana atatu a sayansi ndi wopambana wa ndalama zambiri za sayansi zapadziko lonse ndi mphoto.
Zida
Laborator ili ndi X-ray diffractometer DRON-8 kuchokera ku kampani yaku Russia ya Burevestnik (pamwambapa pa KDPV). Ichi ndi chimodzi mwa zida zazikulu zowunikira zida.
Imathandiza kusonyeza khalidwe la makhiristo ndi ma heterostructures poyesa mawonekedwe a X-ray diffraction. Pochiza matenthedwe amitundu yopyapyala ya semiconductor yomwe ikupangidwa, timagwiritsa ntchito kuyika uku.
Timagwiritsa ntchito makina apamwamba kwambiri oyendetsa ndege kuti azitha kuzindikira, kusintha ndi kukonza ma LED. Tiyeni tikambirane woyamba (chithunzi pansipa kumanzere).
Ichi ndi choperekera molondola . Ndi makina opangira ma viscous liquids. Choperekera chotere ndichofunika kwambiri kuti mugwiritse ntchito molondola zinthu za phosphor ku chip cha LED kuti mukwaniritse mtundu wowala womwe mukufuna.
Poyambirira (mwachisawawa), ma LED oyera omwe timawadziwa amatengera tchipisi tomwe timatulutsa mumtundu wa buluu wowoneka bwino wa radiation yamagetsi.
Chipangizochi (chithunzi chapakati) chimayesa mawonekedwe amagetsi amakono ndi owoneka bwino a tchipisi ta LED ndikusunga zomwe zayezedwa pamakompyuta ambiri. Ndikofunikira kuyang'ana magawo amagetsi ndi kuwala a zitsanzo zopangidwa. Izi ndi zomwe kuyika kumawoneka ngati mutsegula zitseko za buluu:
Chipangizo chachitatu pa chithunzi chonse ndi dongosolo losankhira ndikukonzekera ma LED kuti akhazikitsenso. Kutengera mawonekedwe omwe amayezedwa, amapanga pasipoti ya LED. Wosankhayo amawayika ku gulu limodzi mwa magawo 256 kutengera mtundu wa chipangizo cha semiconductor (gulu 1 ndi ma LED omwe sawala, gulu la 256 ndi omwe amawala kwambiri pamawonekedwe omwe aperekedwa).
Ku International Research Center yathu tikugwiranso ntchito pakukula kwa zida za semiconductor ndi heterostructures. Ma heterostructures amakula pogwiritsa ntchito epitaxy ya molekyulu pa RIBER MBE 49 kukhazikitsa pakampani yolumikizana ndi Connector-Optics.
Kuti tipeze makhiristo amodzi a oxide (omwe ndi ma semiconductors atali-gap) kuchokera kusungunula, timagwiritsa ntchito makina opangira ma multifunctional kukula a NIKA-3. Ma semiconductors a Wide-gap amatha kukhala ndi ntchito pamagetsi am'tsogolo, ma lasers owoneka bwino a VCSEL, zowunikira ma ultraviolet, ndi zina zambiri.
Mapulani
Pamalo a International Scientific Center, labotale yathu imachita kafukufuku wosiyanasiyana wofunikira komanso wogwiritsidwa ntchito.
Mwachitsanzo, pamodzi ndi ofufuza a Ufa State Aviation Technical University, ife okonda zitsulo zatsopano zokhala ndi ma conductivity ochulukirapo komanso mphamvu yayikulu. Kupanga iwo, njira zosinthira kwambiri pulasitiki zimagwiritsidwa ntchito. Kapangidwe kabwino ka aloyi kamakhala ndi chithandizo cha kutentha, komwe kumagawiranso kuchuluka kwa maatomu onyansa muzinthuzo. Zotsatira zake, magawo a conductivity ndi mawonekedwe amphamvu azinthuzo amakhala bwino.
Ogwira ntchito ku labotale akupanganso matekinoloje opangira ma transceivers optoelectronic pogwiritsa ntchito ma frequency ophatikizika a Photonic. Ma transceivers oterowo adzapeza ntchito mumakampani opanga njira zotumizira / kulandira zidziwitso zapamwamba kwambiri. Masiku ano, malangizo akonzedwa kale kuti apange ma prototypes a magwero a radiation ndi photodetectors. Zolemba zopanga zoyeserera zawo zakonzedwanso.
Ntchito yofunikira ya labotale kupanga zida za semiconductor zokhala ndi gap wide-gap ndi ma nanostructures okhala ndi chilema chochepa. M'tsogolomu, pogwiritsa ntchito zipangizo zomwe zikupangidwira, tidzatha kupanga zida zopulumutsa mphamvu za semiconductor zomwe zilibe ma analogue pamsika.
Akatswiri athu atero kale Ma LED, omwe amatha kulowa m'malo mwa nyali za ultraviolet zosatetezedwa za mercury. Phindu la zida zopangidwa ndizomwe zimapangidwira kuti mphamvu zamagulu athu a ultraviolet LED ndizokwera kangapo kuposa mphamvu ya ma LED - 25 W motsutsana ndi 3 W. M'tsogolomu, teknoloji idzapeza ntchito pazaumoyo, chithandizo chamadzi ndi madera ena omwe ma radiation a ultraviolet amagwiritsidwa ntchito.
Gulu la asayansi ochokera ku International Scientific Center yathu kuti zipangizo zamtsogolo za optoelectronic zidzagwiritsa ntchito zinthu zodabwitsa za nano-kakulidwe - madontho a quantum, omwe ali ndi magawo apadera a kuwala. Mwa iwo - kapena kuwala kopanda kutentha kwa chinthu, komwe kumagwiritsidwa ntchito pa TV, mafoni a m'manja ndi zida zina zowonetsera.
Ife kale kupanga zida zofananira za optoelectronic za m'badwo watsopano. Koma zida zisanachitike pamsika, tiyenera kukonza matekinoloje opangira zida ndikutsimikizira chitetezo chazomwe zimapangidwira kwa ogwiritsa ntchito.
Maulendo ena azithunzi zama laboratories athu:
