I-Boron: Kusukela Kuzinto Eziyisisekelo Kuya Ku-High-Tech Core – Ukuhlaziya Ukusetshenziswa Okunembile kwe-High-Purity Boron kuma-Semiconductors kanye nama-Advanced Fields
Emikhakheni yobuchwepheshe obuphezulu ephishekela imikhawulo emincane kanye nokusebenza okuphezulu, izinto ezithile eziyisisekelo zidlala indima ebalulekile.I-Boron,Uphawu lwesakhi B, inombolo ye-athomu 5, luyinye yalezi zinto. Le metalloid, etholakala kuphela kuma-compounds emvelweni, isibe “isakhi esiyisihluthulelo” esibalulekile emikhakheni efana nama-semiconductors, izinto ezithuthukisiwe, kanye nemboni yenuzi ngenxa yesakhiwo sayo esiyingqayizivele se-elekthronikhi kanye nezakhiwo zomzimba nezamakhemikhali.
1. “Izingcweti Zobuciko” Zomkhakha We-Semiconductor: Ukucubungula Ngokunembile Nokukhula Kwekristalu
Embonini ye-semiconductor, inani le-boron ekristalu emsulwa kakhulu lisemakhono ayo okulawula ukunemba okungenakuqhathaniswa.
Isisekelo se-P-type doping: Ukusetshenziswa okuyinhloko kwe-Boron kunjenge-P-type dopant. I-Silicon (Si) iwumsebenzi ongaphikiswana ngawo wezinto ze-semiconductor, kodwa ngokwemvelo ayisebenzi kahle. Lapho ama-athomu e-boron efakwa ngokunembile ku-silicon lattice ngokusebenzisa amasu afana nokufakelwa kwe-ion noma ukusabalala kwezinga lokushisa eliphezulu, igobolondo langaphandle le-boron liqukethe ama-electron amathathu kuphela, uma kuqhathaniswa nama-electron amane e-silicon. Lokhu kudala "umgodi" ongamukela futhi uthwale ama-electron, udale ngempumelelo i-P-type semiconductor. Le nqubo "yokusebenzisa i-doping" iyisisekelo ekwakhiweni kwe-PN junction—isakhiwo esiyisisekelo sawo wonke amadivayisi e-semiconductor, kufaka phakathi ama-diode, ama-transistors, kanye ne-thyristors.
Isihluthulelo samadivayisi kagesi kanye nokukala: Kumadivayisi kagesi okumele amelane nama-voltage aphezulu kanye nemisinga ephezulu (njenge-IGBTs kanye nama-MOSFET amandla), ama-silicon wafers ane-boron-doped (ngokuvamile esifundeni sokumelana okuphezulu) alawula ngempumelelo ukusatshalaliswa kwensimu kagesi futhi athuthukise i-voltage yokumelana nedivayisi. Ngaphezu kwalokho, kuma-node enqubo athuthukile, ukwakheka kwama-junctions angajulile kudinga ukunemba okuphezulu kakhulu kwe-doping. I-Boron, ngenxa ye-radius yayo encane ye-athomu, ivumela ukulawulwa kwe-doping okucolekile, ihlangabezana nezidingo zamadivayisi e-nanoscale.
Izinto zomthombo wokukhula kwekristalu elilodwa: Ngaphezu kokusebenzisa izidakamizwa, i-crystalline boron isetshenziswa futhi njengomthombo wokukhulisa i-boron-dopedi-siliconamakristalu angawodwa ngenqubo yokuncibilika. Le ndlela ikhiqiza ama-silicon ingots anomoya wohlobo lwe-P ofanayo kulo lonke i-wafer, okuhlinzeka ngesisekelo sokukhiqizwa okukhulu kwamadivayisi e-semiconductor ahambisanayo kakhulu.
2. Ngale Kwama-Semiconductors: Ukusebenza Okuhle Kakhulu kukaBoron Emasimini Amaningi
Ukusetshenziswa kweBoron kudlulela ngale kwama-semiconductor; ama-compounds ayo nama-isotope akhanya emikhakheni eminingi ethuthukile.
Izinto Zokwakha Ezithuthukisiwe: Ubulukhuni obukhulu kakhulu be-Boron (ubulukhuni be-Mohs 9.5) buyenza ibe yinto efanelekile yokuqinisa. Imicu ye-Boron kanye ne-boride ceramics ziyizingxenye ezibalulekile ekukhiqizweni kwezinto ezihlanganisiwe ezinamandla aphezulu, ezilula, ezisetshenziswa kabanzi ezindizayo, emishinini yezemidlalo esebenza kahle, nakweminye imikhakha.
Ingilazi Ekhethekile kanye ne-Ceramics: Ekwenziweni kwengilazi, ukungezwa kwe-boron oxide kunciphisa kakhulu i-coefficient yokwanda kokushisa, okunikeza ukumelana okuhle kakhulu kokushaqeka kokushisa. Le ngilazi ye-borosilicate iyisinqumo esikhethwayo sezinto zelebhu (ezifana nama-beakers amelana nokushisa) kanye nezitsha zokupheka ezisezingeni eliphezulu. Ngokufanayo, ukungezwa kwamakhemikhali e-boron ku-ceramics kuthuthukisa ukuzinza kwawo kokushisa kanye namandla okusebenza.
Ukubanjwa kwe-neutron kanye nemboni yenuzi: I-boron yemvelo iqukethe cishe u-20% we-isotope ye-boron-10, enesigaba sokubamba esiphezulu kakhulu sama-neutron ashisayo. Lesi sici senza i-boron-10 (ngokuvamile ngesimo se-boron carbide noma i-boric acid) ibe yinto ebalulekile yokulawula induku, into yokuvikela i-neutron, kanye ne-ejenti yokuphepha yezinhlelo zokuvala eziphuthumayo kuma-reactor enuzi.
Ukwenziwa Kwezinto Eziphilayo kanye Nemithi: Emikhakheni emihle yamakhemikhali kanye nemithi, ama-reagent aqukethe i-boron (njenge-boronic acid kanye nama-boronic esters) ayizinto ezibalulekile zokwakha izibopho ze-carbon-carbon kanye ne-carbon-heteroatom, ikakhulukazi ekusabeleni kokuxhumanisa kwe-Suzuki-Miyaura. Inani elikhulayo lama-molecule e-organic aqukethe i-boron ayathuthukiswa njengemithi emisha. Isibonelo, ezinye izithibi ze-proteasome sezibe izindlela zokwelapha ezibalulekile zokulwa nomdlavuza.
3. Ikhwalithi iyitshe lesisekelo lobuchwepheshe: ukunikezwa okuthembekile okuvela eShayina
Njengoba ibhekene nokusetshenziswa okubanzi nokufuna ubuchwepheshe obuphezulu, izidingo zokuhlanzeka, ukuvumelana kanye nesimo esithile (njengosayizi wezinhlayiya kanye nesimo sekristalu) sezinto ze-boron zifinyelele amazinga angakaze abonwe.
I-UrbanMines Tech., umkhiqizi ohamba phambili nomhlinzeki wezinto ze-boron ezihlanzekile kakhulu eShayina, uyaqonda ngokujulile umthelela obalulekile wezakhiwo zezinto ezibonakalayo emikhiqizweni engezansi. Sisebenzisa imigqa yethu yokukhiqiza eyimfihlo nelawulwayo, sigxile ekuhlinzekeni i-boron ekristalu ehlanzekile kakhulu kanye ne-boron engabonakali kahle yezinga le-semiconductor, kanye nama-compound e-boron enziwe ngokwezifiso ahlukahlukene, kumakhasimende emhlabeni jikelele.
Sikholelwa ngokuqinile ukuthi imikhiqizo emihle kakhulu kuphela engahlangabezana nezidingo zobuchwepheshe obusezingeni eliphezulu. Ngakho-ke, sizibophezele ekusebenzisaneni eduze nabalingani bomhlaba wonke be-R&D kanye nokukhiqiza ukuze sifinyelele imingcele yobuchwepheshe ngokubambisana, kusukela kuma-chips kuya emandleni ahlanzekile, ngokunikeza izixazululo zezinto ze-boron ezisebenza kahle kakhulu, ezizinzile nezithembekile.
