Hauv thaj chaw ntawm kev tsim khoom siv siab heev, kev sib koom ua ke tob ntawmkev siv tshuab nqus tsev thiab nanotechnologyytab tom tsav tsheb txoj kev vam meej hauv kev ua haujlwm ntawm qhov chaw thiab kev tsim cov khoom siv ua tau zoo. Los ntawm kev siv cov txheej txheem siab heev xws li Physical Vapor Deposition (PVD), Chemical Vapor Deposition (CVD), thiab Atomic Layer Deposition (ALD) hauv cov chaw muaj cua sov siab, peb tuaj yeem ua tiav kev tswj hwm cov khoom siv, cov qauv, thiab morphology ntawm nanoscale. Qhov kev sib koom ua ke no tsis yog tsuas yog hla dhau qhov kev txwv kev ua tau zoo ntawm cov txheej txheem ib txwm muaj tab sis kuj tseem tso lub hauv paus ruaj khov rau kev tsim cov khoom siv nano tiam tom ntej.
Kev Tswj Xyuas Kom Zoo ntawm Nanoscale Thin Film Deposition
Cov txheej txheem txheej txheej nqus tsev, suav nrog magnetron sputtering, electron beam evaporation, thiab pulsed laser deposition (PLD), tau dhau los ua cov txheej txheem tseem ceeb rau kev tsim cov nanomultilayers, superlattice structures, thiab quantum dot arrays vim lawv cov yeeb yaj kiab zoo sib xws, qhov tsis zoo tsawg, thiab kev nplaum zoo dua. Los ntawm kev kho cov txheej txheem deposition (xws li qhov kub ntawm substrate, kev ua haujlwm siab, thiab lub zog plasma), kev tswj hwm qhov tuab ntawm zaj duab xis los ntawm sub-nanometer mus rau ntau pua nanometers tuaj yeem ua tiav, ua tau raws li cov kev cai nruj rau cov lim dej optical, cov txheej txheem tiv thaiv tawv, thiab Micro-Electro-Mechanical Systems (MEMS) cov khoom siv.
Kev Tso Tawm Txheej Atomic: Kev Hloov Pauv Nanoscale Encapsulation thiab 3D Cov Qauv
ALD thev naus laus zis, los ntawm kev txwv tus kheej cov tshuaj lom neeg saum npoo av, ua rau muaj kev npog zaj duab xis nyias nyias ntawm cov qauv peb-seem uas nyuaj. Cov yam ntxwv no ua rau nws tseem ceeb rau kev hloov kho cov ntaub ntawv nanoporous, txheej cov qauv siab-piv txwv, thiab kev tsim cov electrode / electrolyte interfaces hauv cov khoom siv khaws cia lub zog (piv txwv li, txhua lub roj teeb khov kho). Piv txwv li, hauv cov roj teeb lithium-ion, ALD-deposited nanolayers ntawm alumina lossis hafnia tuaj yeem txhim kho qhov thermal stability thiab lub neej voj voog ntawm cov ntaub ntawv cathode.
Kev Tsim Kho Cov Nanostructures Ua Haujlwm
Ua ke nrog cov txheej txheem kev pabcuam template thiab nanolithography, txheej txheej nqus tsev tuaj yeem pab txhawb kev loj hlob ntawm nanowires, nanotubes, thiab nanopore arrays. Cov qauv zoo li no qhia tau tias muaj peev xwm zoo hauv cov sensors surface plasmon resonance (SPR), catalytic converters, thiab high-performance transistors. Piv txwv li, siv reactive sputtering los tso titanium dioxide nanotube arrays hauv anodic aluminium oxide (AAO) templates tuaj yeem txhim kho qhov ua tau zoo ntawm photocatalytic degradation.
Kev Xav Tau Daim Ntawv Thov Yav Tom Ntej
Nrog kev tsim kho tshiab tas mus li hauv nanotechnology thiab lub tshuab nqus tsev, cov teb tshiab xws li cov tshuab ntse teb tau sai, cov khoom siv hluav taws xob yooj ywm, thiab cov khoom siv quantum computing tau npaj rau kev nce qib tshiab. Los ntawm kev ua kom zoo dua ntawm kev sib koom ua ke thiab kev sib txuas lus, peb tab tom txuas qhov sib txawv ntawm "microstructural design" mus rau "macroscopic performance customization," muab cov kev daws teeb meem hloov pauv rau kev lag luam suav nrog aerospace, biomedical, thiab lub zog ruaj khov.
