Lefapheng la boenjiniere ba thepa e tsoetseng pele, kopanyo e tebileng eatheknoloji ea ho koahela ka vacuum le nanotechnologyye kganna kgatelopele e kgolo tshebetsong ya bokahodimo le moralo wa thepa e sebetsang hantle. Ka ho sebedisa ditshebetso tse tswetseng pele tse kang Physical Vapor Deposition (PVD), Chemical Vapor Deposition (CVD), le Atomic Layer Deposition (ALD) dibakeng tse nang le vacuum e ngata, re ka fihlella taolo e nepahetseng hodima sebopeho sa thepa, sebopeho le sebopeho sa nanoscale. Tshebedisano ena e kopaneng ya dithuto ha e fete feela meedi ya tshebetso ya dikobo tsa setso empa hape e beha motheo o tiileng bakeng sa tlhahiso ya di-nanodevices tsa moloko o latelang.
Taolo e Nepahetseng ea Nanoscale Thin Film Deposition
Mekhoa ea ho koahela ka vacuum, ho kenyeletsoa le ho sputtering ea magnetron, mouoane oa mahlaseli a electron, le pulsed laser deposition (PLD), e se e le mekhoa ea mantlha ea ho etsa li-nanomultilayers, meaho ea superlattice, le li-array tsa quantum dot ka lebaka la ho tšoana ha tsona ho ikhethang ha filimi, bongata bo fokolang ba sekoli, le ho khomarela ho phahameng. Ka ho fetola liparamente tsa deposition (tse kang mocheso oa substrate, khatello ea ho sebetsa, le matla a plasma), taolo e nepahetseng ea botenya ba filimi ho tloha ho sub-nanometer ho ea ho makholo a nanometer e ka finyelloa, ho fihlela litlhoko tse thata tsa li-filter tsa optical, li-coat tse sireletsang ka thata, le lisebelisoa tsa Micro-Electro-Mechanical Systems (MEMS).
Ho Hlahisa Lera la Atomo: Ho Fetola ho Hlahisa ha Nanoscale le Dibopeho tsa 3D
Theknoloji ea ALD, ka liketso tsa lik'hemik'hale tse ipehelang meeli holim'a metsi, e nolofalletsa ho koahela filimi e tšesaane ka ho nepahala ha athomo meahong e rarahaneng ea mahlakore a mararo. Tšobotsi ena e etsa hore e be ea bohlokoa bakeng sa ho fetola thepa e nang le masoba a mabeli, ho koahela mehaho ea karolelano ea likarolo tse phahameng, le li-interface tsa boenjiniere ba electrode/electrolyte lisebelisoa tsa polokelo ea matla (mohlala, libeteri tsa boemo bo tiileng). Mohlala, libetering tsa lithium-ion, li-nanolayers tse bolokiloeng ke ALD tsa alumina kapa hafnia li ka ntlafatsa haholo botsitso ba mocheso le bophelo ba potoloho ea thepa ea cathode.
Kaho e Laoloang ea Meaho e Sebetsang ea Nano
Ha e kopantsoe le mekhoa ea ho beha ka thuso ea template le nanolithography, ho koahela ka vacuum ho ka thusa haholo kholo e lebisitsoeng ea li-nanowire, li-nanotubes le li-nanopore arrays. Meaho e joalo e bontša bokhoni bo boholo ho li-sensor tsa plasmon resonance (SPR), li-catalytic converter le li-transistors tse sebetsang hantle. Mohlala, ho sebelisa reactive sputtering ho kenya li-nanotube arrays tsa titanium dioxide ka har'a li-template tsa anodic aluminium oxide (AAO) ho ka ntlafatsa haholo katleho ea ho senyeha ha photocatalytic.
Litebello tsa Kopo tse shebaneng le Bokamoso
Ka boqapi bo tswelang pele ho theknoloji ya nanotechnology le ho kwahela ka vacuum, masimo a hlahang a kang ho kwahela ka bohlale, disebediswa tsa elektroniki tse tenyetsehang, le dikarolo tsa khomphutha ya quantum di se di loketse kgatelopele e kgolo. Ka ntlafatso ya tshebedisano mmoho ya kopanyo ya tekanyo e pharaletseng le boenjiniere ba sebopeho, re ntse re kwala sekgeo ho tloha ho "moralo wa meaho e menyenyane" ho ya ho "ho fetola tshebetso ya macroscopic," re fana ka ditharollo tse fetolang bakeng sa diindasteri ho kenyeletswa le sefofane, tsa bongaka le matla a tswelang pele.
