Electron bincike da madubin likita - nanotechnology kayan aiki

Electron bincike da madubin likita ne mai hade da electron-bincike da hanyoyin gudanar da bincike da microstructure na daskararru, kazalika da abun da ke ciki da kuma gida microscopic filin.

Idan wannan hanyar bincike amfani da musamman kayan - microscopes, da siffar da aka karu da gaban electron bim.

Electron bincike da madubin likita biyu main yankunan:

• Transmission - ta hanyar transmissive na'urar hange a wadda translucent abubuwa da wani electron katako da ciwon wani makamashi na 50 zuwa 200 keV. A electrons da cewa ratsa cikin abu a karkashin binciken, samun on na musamman Magnetic ruwan tabarau. Wadannan ruwan tabarau suna kafa a kan wani musamman allo ko daukar hoto fim image na ciki Tsarin daga cikin abu. Dole ne in ce cewa baza electron bincike da madubin likita sa ya yiwu a samu wani karuwa kusan 1.5 sau * 106. Yana samar da wata dama ga hukunci da crystalline tsarin da abubuwa da aka haka dauke da farko hanya domin karatu ultrathin Tsarin daban-daban daskararru.

• Ana dubawa (scanning) electron bincike da madubin likita - yana da za'ayi ta wajen musamman microscopes, a cikin abin da electron katako ta yin amfani da Magnetic ruwan tabarau ne aka tattara a cikin wani bakin ciki bincike. Yana yin sikanin surface na abu, cikinsa da sakandare radiation ya auku, wanda aka gano da daban-daban gane da kuma tuba a cikin jerin sakonni.

Ya kamata a lura cewa na'urar hange na da yawan abũbuwan amfãni a kan gargajiya da hanyoyin da X-ray microanalysis. Wannan shi ne dalilin da ya sa shi ne mafi zama na kowa da za a iya kira wata babbar nasara na zamani nanotechnology.

Bugu da kari, electron bincike da madubin likita sa m ci gaban da kwamfuta morphometry, jigon wanda yake shi ne yin amfani da fasahar kwamfuta domin karin sosai, kuma da cikakken aiki na hotunan lantarki.

Don kwanan wata, ɓullo da wani hardware-software da tsarin, wanda suke iya adana su da hotuna da kuma gudanar da ilimin kididdiga aiki, daidaita bambanci da kuma haske, zaɓi mutum aka gyara diddigin microstructures.

Modern electron microscopes suna sanye take da musamman sarrafawa cewa rage alama na lalacewar gwada abu samfurori, kazalika da kara daidaito na bayanin a kan bincike na da microstructure na abubuwa, wanda ƙwarai facilitates aikin bincike.

electron microanalysis nasarori ake amfani a baje na fahimtar nukiliya interactions, wanda ba ka damar haifar da wani abu da labari Properties, da kuma wani m uku-girma tallan kayan kawa damar masana kimiyyar gudanar da bincike da muhimmanci kwayoyin sunadaran da cewa underlie duk nazarin halittu tafiyar matakai. Bugu da kari, ta hanyar amfani da electron bincike da madubin likita, yana yiwuwa a gudanar da wani yawan tsauri gwaje-gwajen da kuma samun zama dole dalilin da zane na sabuwar nanostructures.
