Ua hana mua mākou i kahi huakaʻi kiʻi liʻiliʻi ma Habré. Hōʻike ʻia kā mākou , nana aku la i loko o ka hale hana robotics a nānā i kā mākou kumuhana .
I kēia lā e haʻi mākou iā ʻoe i ka mea (a he aha) kekahi o kā mākou laboratories ma ka International Scientific Center for Functional Materials and Optoelectronics Devices e hana nei.
Ma ke kiʻi: X-ray diffractometer DRON-8
He aha kā lākou hana ma ʻaneʻi?
Ua wehe ʻia ke keʻena ʻo "Advanced Nanomaterials and Optoelectronic Devices" ma ke kumu o ka International Scientific Center, e pili ana me nā mea hou, me nā semiconductors, nā metala, nā oxides i kahi moku nanostructured, no ke kumu o kā lākou hoʻohana ʻana i nā mea optoelectronic a me nā mea hana.
Nā haumāna, nā haumāna puka a me nā limahana keʻena hoʻokolohua nā waiwai o nā nanostructure a hana i nā mea semiconductor hou no ka micro- a me ka optoelectronics. Hoʻohana ʻia nā mea hoʻomohala ma ke kahua o nā kukui LED e pono ai ka ikehu a e koi ʻia i ka wā e hiki mai ana i nā uila uila kiʻekiʻe no nā grids akamai ().
Ma ke kaiāulu haumāna, ua kapa ʻia ka kahua noiʻi ma ke alanui Lomonosov, hale 9 "ʻO ka hale hana ʻo Romanov", no ka mea, ua alakaʻi ʻia ka Laboratory a me ka Center e - , Kauka o Physical and Mathematics Sciences, alakaʻi polopeka a me dean o ke Kumu o Laser Photonics a me Optoelectronics ma ITMO University, mea kākau o oi aku ma mua o XNUMX 'epekema paʻi a me ka lanakila o ka nui honua 'epekema haawi a me nā makana.
Kākoʻo
He X-ray diffractometer DRON-8 mai ka hui Lūkini Burevestnik (ma luna o KDPV). ʻO kēia kekahi o nā mea hana nui no ka nānā ʻana i nā mea.
Kōkua ia i ka hoʻohālikelike ʻana i ka maikaʻi o nā kristal a me nā heterostructures e ana ʻia ma ke ana ʻana i ka spectra diffraction X-ray. No ka mālama wela o nā hale semiconductor kiʻiʻoniʻoni lahilahi e kūkulu ʻia ana, hoʻohana mākou i kēia hoʻonohonoho hale.
Hoʻohana mākou i nā ʻōnaehana pilot-scale hou e hoʻohālikelike, hoʻololi a hoʻokaʻawale i nā LED. E kamaʻilio kākou e pili ana i ka mea mua (ke kiʻi ʻia ma lalo ma ka ʻaoʻao hema).
He dispenser pololei kēia . He ʻōnaehana automated no ka hāʻawi ʻana i nā wai viscous. He mea koʻikoʻi kēlā dispenser no ka hoʻopili pololei ʻana i nā mea phosphor i kahi chip LED i mea e hoʻokō ai i ke kala ʻulaʻula i makemake ʻia.
ʻO ka hoʻomaka (ma ka maʻamau), ʻo nā LED keʻokeʻo a mākou i kamaʻāina e pili ana i nā chips e hoʻopuka ana i ka laulā polū o ka spectrum ʻike ʻia o ka radiation electromagnetic.
ʻO kēia mea hana (ma ke kiʻi maʻamau ma ke kikowaena) e ana i nā hiʻohiʻona o kēia manawa a me nā hiʻohiʻona o nā pahu LED a mālama i nā ʻikepili i ana ʻia no ka nui o nā chips i ka hoʻomanaʻo kamepiula. Pono ia e nānā i nā ʻāpana uila a me ka optical o nā laʻana i hana ʻia. ʻO kēia ke ʻano o ka hoʻonohonoho ʻana inā wehe ʻoe i nā puka uliuli:
ʻO ke kolu o ka mea hana ma ke kiʻi maʻamau he ʻōnaehana no ka hoʻokaʻawale ʻana a me ka hoʻomākaukau ʻana i nā LED no ka hoʻokomo ʻana. Ma muli o nā ʻano i ana ʻia, hōʻuluʻulu ʻo ia i kahi passport no ka LED. Hāʻawi ka sorter iā ia i hoʻokahi o 256 mau ʻāpana e pili ana i ka maikaʻi o ka mea semiconductor (ʻo ka ʻāpana 1 nā LED ʻaʻole ʻālohilohi, ʻo ka māhele 256 nā mea e ʻālohilohi loa i kahi ākea spectral i hāʻawi ʻia).
Ma kā mākou International Research Center ke hana pū nei mākou i ka ulu ʻana o nā mea semiconductor a me nā heterostructures. Hoʻoulu ʻia nā Heterostructures me ka hoʻohana ʻana i ka molecular beam epitaxy ma kahi hoʻonohonoho RIBER MBE 49 ma ka hui hui Connector-Optics.
No ka loaʻa ʻana o nā kristal hoʻokahi oxide (ʻo ia nā semiconductors ākea ākea) mai ka hoʻoheheʻe ʻana, hoʻohana mākou i kahi hoʻonohonoho ulu multifunctional ulu NIKA-3. Loaʻa paha nā semiconductors ākea ākea i nā noi i nā relay mana e hiki mai ana, nā lasers VCSEL kūpaʻa kiʻekiʻe, nā mea ʻike ultraviolet, etc.
Nā Pāhana
Ma nā kahua o ka International Scientific Center, hana kā mākou hale hana i nā ʻano noiʻi kumu a noiʻi.
No ka laʻana, me nā mea noiʻi mai ka Ufa State Aviation Technical University, mākou nā conductors metala hou me ka hoʻonui i ka conductivity a me ka ikaika kiʻekiʻe. No ka hana ʻana iā lākou, hoʻohana ʻia nā ʻano o ka deformation plastic koʻikoʻi. Hoʻopili ʻia ke ʻano o ka huila i ka hoʻomaʻamaʻa wela, ka mea e hāʻawi hou i ka neʻe ʻana o nā atoms haumia i loko o ka mea. ʻO ka hopena, ua hoʻomaikaʻi ʻia nā ʻāpana conductivity a me nā ʻano ikaika o ka mea.
Ke hoʻomohala nei nā limahana Laboratory i nā ʻenehana no ka hana ʻana i nā transceivers optoelectronic me ka hoʻohana ʻana i nā kaapuni hoʻohui photonic. E loaʻa i kēlā mau transceivers ka noi ma ka ʻoihana o ka hana ʻana i nā ʻōnaehana hoʻouna / hoʻokipa kiʻekiʻe. I kēia lā, ua hoʻomākaukau mua ʻia kahi papa kuhikuhi no ka hana ʻana i nā prototypes o nā kumu radiation a me nā photodetectors. Ua hoʻomākaukau ʻia nā palapala hoʻolālā no kā lākou hoʻāʻo ʻana.
Papahana hale hana nui ka hana ʻana i nā mea semiconductor ākea ākea a me nā nanostructure me ka haʻahaʻa haʻahaʻa haʻahaʻa. I ka wā e hiki mai ana, me ka hoʻohana ʻana i nā mea i hoʻomohala ʻia, hiki iā mākou ke hana i nā mea hana semiconductor mālama i ka ikehu i loaʻa ʻole nā analogues ma ka mākeke.
Ua loaʻa i kā mākou poʻe loea Nā LED, hiki ke hoʻololi i nā kukui ultraviolet i hoʻokumu ʻia me ka mercury. Aia ka waiwai o nā mea i hana ʻia i ka mana o kā mākou hui ultraviolet LED he mau manawa kiʻekiʻe ma mua o ka mana o kēlā me kēia LED - 25 W versus 3 W. I ka wā e hiki mai ana, e ʻike ka ʻenehana i ka noi i ka mālama olakino, mālama wai a me nā wahi ʻē aʻe kahi e hoʻohana ʻia ai ka radiation ultraviolet.
He pūʻulu ʻepekema mai kā mākou International Scientific Center e hoʻohana nā mea optoelectronic i ka wā e hiki mai ana i nā waiwai kupaianaha o nā mea nano-nui - nā kiko kiko, nona nā ʻāpana optical kūikawā. Ma waena o lākou - a i ʻole ka wela wela ʻole o kekahi mea, i hoʻohana ʻia i nā kīwī, kelepona a me nā hāmeʻa ʻē aʻe me nā hōʻike.
Loaʻa mākou ka hana ʻana o nā mea like optoelectronic o kahi hanauna hou. Akā ma mua o ka paʻi ʻana o nā hāmeʻa i ka mākeke, pono mākou e hana i nā ʻenehana no ka hana ʻana i nā mea a hōʻoia i ka palekana o nā mea i loaʻa no nā mea hoʻohana.
Nā huakaʻi kiʻi ʻē aʻe o kā mākou mau keʻena hana:
