Ib qho txuj ci tseem ceeb hauv thaj chaw ntawm cov ntaub ntawv ua haujlwm
Ua ib tugpob zeb diamonddaim ntawv thov, nws cuam tshuam nrog ntau yam thev naus laus zis thiab nyuaj heev. Nws yuav tsum tau ua kev tshawb fawb koom tes hauv ntau qhov chaw kom ua tiav hauv lub sijhawm luv luv. Yav tom ntej, nws yog qhov tsim nyog los txuas ntxiv txhim kho thiab txhim kho CVD pob zeb diamond kev loj hlob thev naus laus zis thiab tshawb nrhiav kev siv ntawmPob zeb diamond CVDzaj duab xis hauv acoustics, optics, thiab hluav taws xob. Nws yuav dhau los ua cov khoom siv tshiab rau kev txhim kho thev naus laus zis siab hauv xyoo pua 21st. Daim ntawv thov ntawm CVD tuaj yeem siv rau ob qho tib si cov ntaub ntawv engineering thiab cov ntaub ntawv ua haujlwm. Cov hauv qab no tsuas yog kev qhia txog nws cov ntawv thov ua haujlwm.
Cov khoom siv ua haujlwm yog dab tsi? Cov khoom siv ua haujlwm yog hais txog ntau yam khoom siv uas muaj lub cev thiab tshuaj ua haujlwm xws li lub teeb, hluav taws xob, hlau nplaum, suab, thiab cua sov siv hauv kev lag luam thiab thev naus laus zis, suav nrog cov khoom siv hluav taws xob, cov khoom siv hlau nplaum, cov khoom siv kho qhov muag, cov khoom siv superconducting, cov khoom siv biomedical, cov ntaub ntawv ua haujlwm, thiab lwm yam.
Lub membrane ua haujlwm yog dab tsi? Nws cov yam ntxwv yog dab tsi? Lub membrane ua haujlwm yog hais txog cov khoom siv nyias nyias nrog cov khoom siv lub cev xws li lub teeb, magnetism, kev lim hluav taws xob, kev nqus, thiab cov khoom siv tshuaj xws li catalysis thiab kev ua haujlwm.
Cov yam ntxwv ntawm cov ntaub ntawv zaj duab xis nyias: Cov ntaub ntawv zaj duab xis nyias yog cov ntaub ntawv ob-seem, uas yog, lawv loj ntawm ob qhov ntsuas thiab me ntawm qhov ntsuas thib peb. Piv nrog rau cov ntaub ntawv peb-seem uas siv ntau, nws muaj ntau yam ntxwv hauv kev ua tau zoo thiab cov qauv. Qhov tshwj xeeb tshaj plaws yog tias qee yam khoom ntawm cov yeeb yaj kiab ua haujlwm tuaj yeem ua tiav los ntawm cov txheej txheem npaj zaj duab xis nyias tshwj xeeb thaum lub sijhawm npaj. Qhov no yog vim li cas cov ntaub ntawv ua haujlwm zaj duab xis nyias tau dhau los ua lub ntsiab lus kub ntawm kev saib xyuas thiab kev tshawb fawb.
Ua ib tugcov khoom siv ob sab, qhov tseem ceeb tshaj plaws ntawm cov ntaub ntawv zaj duab xis nyias yog qhov hu ua qhov loj me, uas tuaj yeem siv los ua kom me me thiab sib xyaw ua ke ntau yam khoom. Ntau yam kev siv ntawm cov ntaub ntawv zaj duab xis nyias yog raws li qhov no, qhov feem ntau yog siv rau hauv cov voj voog sib xyaw thiab kom nce qhov ceev ntawm cov khoom khaws cia hauv computer.
Vim yog qhov me me, qhov sib piv ntawm qhov chaw thiab qhov sib txuas hauv cov khoom siv zaj duab xis nyias yog qhov loj heev, thiab cov khoom uas pom los ntawm qhov chaw yog qhov tseem ceeb heev. Muaj ntau yam teebmeem lub cev ntsig txog qhov sib txuas ntawm qhov chaw:
(1) Kev xaiv xa thiab kev cuam tshuam los ntawm lub teeb cuam tshuam;
(2) Kev tawg tsis sib xws los ntawm kev sib tsoo ntawm cov electrons thiab qhov chaw ua rau muaj kev hloov pauv ntawm kev coj ua, Hall coefficient, tam sim no magnetic teb nyhuv, thiab lwm yam.;
(3) Vim tias cov zaj duab xis tuab me dua li txoj kev dawb ntawm cov electrons thiab nyob ze rau Drobyi wavelength ntawm cov electrons, cov electrons txav mus los ntawm ob sab ntawm zaj duab xis yuav cuam tshuam, thiab lub zog cuam tshuam rau kev txav ntsug ntawm qhov chaw yuav siv cov nqi sib cais, uas yuav cuam tshuam rau kev thauj mus los ntawm electron;
(4) Ntawm qhov chaw, cov atoms raug cuam tshuam tsis tu ncua, thiab qib zog ntawm qhov chaw thiab tus lej ntawm cov xwm txheej ntawm qhov chaw tsim tawm yog tib qho kev txiav txim siab ntawm qhov loj li tus lej ntawm cov atoms ntawm qhov chaw, uas yuav muaj kev cuam tshuam loj rau cov ntaub ntawv uas muaj ob peb tus neeg nqa khoom xws li semiconductors;
(5) Tus naj npawb ntawm cov atoms nyob sib ze ntawm cov atoms magnetic nto txo qis, ua rau lub sijhawm magnetic ntawm cov atoms nto nce ntxiv;
(6) Anisotropy ntawm cov ntaub ntawv nyias nyias, thiab lwm yam.
Vim tias qhov kev ua tau zoo ntawm cov ntaub ntawv zaj duab xis nyias raug cuam tshuam los ntawm cov txheej txheem npaj, feem ntau ntawm lawv nyob rau hauv lub xeev tsis sib npaug thaum lub sijhawm npaj. Yog li ntawd, cov khoom sib xyaw thiab cov qauv ntawm cov ntaub ntawv zaj duab xis nyias tuaj yeem hloov pauv ntau yam yam tsis raug txwv los ntawm lub xeev sib npaug. Yog li ntawd, tib neeg tuaj yeem npaj ntau yam khoom siv uas nyuaj rau ua tiav nrog cov ntaub ntawv loj thiab tau txais cov khoom tshiab. Qhov no yog ib qho tseem ceeb ntawm cov ntaub ntawv zaj duab xis nyias thiab yog ib qho laj thawj tseem ceeb vim li cas cov ntaub ntawv zaj duab xis nyias nyiam tib neeg lub siab. Txawm hais tias siv tshuaj lom neeg lossis lub cev, cov zaj duab xis nyias tsim tuaj yeem tau txais.
