Kuyini ukunemba kwe-electron kanye ne-microscopy elula, ngokulandelana

Ukunemba kwama-electron kanye nama-microscopes optical kuyahlukahluka kuye ngohlobo kanye nomklamo, kanje:

Ukunemba kwe-electron microscopy

I-transmission electron microscopy (TEM): Njengamanje, ukunemba kwesinqumo se-transmission electron microscopy kukwazile ukuxazulula izakhiwo ezingaphansi kuka-0.2μm, kanti isinqumo somkhawulo we-polar singafinyelela ku-0.1nm. Isibonelo, amanye ama-transmission electron microscope amahle anesinqumo esingu-1.5 kuya ku-2A (1A = 0.1nm), esingaxazulula cishe wonke ama-athomu.

Ukuskena nge-electron microscopy (SEM): Isixazululo sendawo esingu-1μm³ sivame ukutholakala, yize ukunemba kungahluka kuye ngohlobo lwemishini kanye nezimo zokubuka.

Ukunemba kwe-microscopy ekhanyayo

I-microscopy ejwayelekile ye-optical: isinqumo sayo esilinganiselwe ngokuvamile singama-250nm, okuphindwe izikhathi eziyisigidi kunesinqumo seso lomuntu (0.25mm). Kodwa-ke, isinqumo kanye nokukhulisa i-microscopy ye-optical kungathuthukiswa kakhulu ngokusebenzisa amalensi anembe kakhulu kanye namasu okukhanya.

I-microscope ecacile kakhulu: njenge-microscope yedijithali ebonakalayo, ukunemba kwayo kwesisombululo kungafinyelela ku-0.1μm, ukukhulisa kufikela ezikhathini ezingu-5000. Ngaphezu kwalokho, kunezinsimbi zokuhlaziya ezicacile kakhulu ezisekelwe esimisweni sokuphazamiseka kokukhanya okumhlophe njenge-microscopy ye-optical enezinhlangothi ezintathu, engafinyelela ukulinganiswa kwe-surface topography ngesisombululo se-subnanometer.

I-microscopy ekhethekile yokukhanya: njenge-nanoscopy yokukhanya enokunemba kokubeka okungu-2nm, njengobuchwepheshe be-MINFLUX, okubonisa ukuthi i-microscopy yokuxazulula i-nanoscale isingene ngokusemthethweni emkhakheni wocwaningo lwesayensi yokuphila.
