Elekitironi wamamamayikirosikopu - nanotechnology chida

Elekitironi wamamamayikirosikopu ndi osakaniza njira zinthu zosiyanasiyana za kafukufuku kufufuza microstructure wa zolimba, komanso zikuchokera awo ndi m'dera munda tosaoneka.

Ngati njira imeneyi kufufuza ntchito zida wapadera - microscopes, imene fano ndi chinawonjezeka ndi kukhalapo kwa milimo elekitironi.

Elekitironi wamamamayikirosikopu ali mbali ziwiri:

• Kufala - kudzera mwa transmissive elekitironi maso imene translucent zinthu ndi elekitironi mtanda ali ndi mphamvu 50 200 keV. The ma elekitironi kuti kudutsa chinthu pansi kuphunzira, kutenga pa magalasi wapadera maginito. magalasi awa anapanga pa TV wapadera kapena Zithunzi filimu chifaniziro cha nyumba mkati wa chinthu. Ine ndiyenera kunena kuti kufala elekitironi wamamamayikirosikopu limachititsa kupeza ponso pafupifupi 1.5 nthawi * 106. Limawapatsa mpata kuweruza crystalline dongosolo la zinthu Choncho ankaona njira yaikulu akuphunzira ultrathin nyumba zolimba zosiyanasiyana.

• kupanga sikani (chindodo) elekitironi wamamamayikirosikopu - ikuchitika mwa microscopes yapadera, imene elekitironi mtengo pogwiritsa ntchito magalasi maginito Akusonkhanitsa mu kafukufuku woonda. Iwo mapanga sikani pamwamba pa chinthu, mmene cheza sekondale zikachitika, amene wapezeka ndi zoyesera osiyana ndi n'kukhala chizindikiro kake.

Tikumbukenso kuti elekitironi maso ali m'njira zambiri pa njira za makolo a X-ray microanalysis. N'chifukwa chake likupitirirabe wamba ndi angatchedwe kupambana yaikulu ya nanotechnology ano.

Komanso, elekitironi wamamamayikirosikopu amapanga kwambiri chitukuko cha kompyuta morphometry, akamanena za ndilo ntchito makompyuta kwa bwino ndi wathunthu processing mafano amagetsi.

Pakali pano, anayamba machitidwe hardware-mapulogalamu, okhoza kusunga zithunzi zawo ndi kuchita processing awo zowerengera, kusintha kusiyana ndi kuwala, sankhani munthu zigawo zikuluzikulu ankafufuza microstructures.

Modern elekitironi microscopes zili ndi mapurosesa wapadera kuti asapatsidwe kuwonongeka kuyesa zitsanzo chuma, komanso ikhale yolondola kwambiri mfundo za Kupenda microstructure wa zinthu, zomwe kwambiri facilitates ntchito ofufuza.

elekitironi microanalysis zikayenda bwino ntchito yaikulu kumvetsa ankachita nyukiliya, zomwe zimathandiza kuti akonze zinthu ndi katundu buku, ndi kupata atatu azithunzi omwe tikunena mawerengeredwe zimathandiza akatswiri kufufuza njira zofunika maselo kuti chimayambitsa njira amalandira. Komanso, pogwiritsa ntchito elekitironi wamamamayikirosikopu, n'zotheka kuchita zingapo zazikulu zatsopano ndi kupeza maziko zofunika kamangidwe ka nanostructures latsopano.
