Yintoni ukuchaneka kwe-electron kunye ne-microscopy yokukhanya, ngokulandelelanayo

Ukuchaneka kwee-electron kunye nee-optical microscopes kuyahluka ngokuxhomekeke kuhlobo kunye noyilo, ngolu hlobo lulandelayo:

Ukuchaneka kwe-electron microscopy

I-transmission electron microscopy (TEM): Okwangoku, ukuchaneka kwesisombululo se-transmission electron microscopy kuye kwakwazi ukusombulula izakhiwo ezingaphantsi kwe-0.2μm, kwaye isisombululo somda we-polar sinokufikelela kwi-0.1nm. Umzekelo, ezinye ii-transmission electron microscopes ezilungileyo zinesisombululo se-1.5 ukuya kwi-2A (1A = 0.1nm), esinokusombulula phantse zonke ii-athomu.

Ukuskena nge-electron microscopy (SEM): Isisombululo sendawo se-1μm³ sidla ngokufezekiswa, nangona ukuchaneka kunokwahluka ngokuxhomekeke kuhlobo lwesixhobo kunye neemeko zokubukela.

Ukuchaneka kwe-microscopy yokukhanya

I-microscopy ye-optical eqhelekileyo: isisombululo sayo esilinganiselweyo sidla ngokuba malunga ne-250nm, esiphindwe ngesigidi kunesisombululo seliso lomntu (0.25mm). Nangona kunjalo, isisombululo kunye nokwandiswa kwe-optical microscopy kunokuphuculwa kakhulu ngokusebenzisa iilensi ezichanekileyo kunye neendlela zokukhanya.

I-microscope ecacileyo kakhulu: njenge-microscope yedijithali ebonakalayo, ukuchaneka kwayo kwesisombululo kunokufikelela kwi-0.1μm, ukwandiswa ukuya kuthi ga kwi-5000 amaxesha. Ukongeza, kukho izixhobo zohlalutyo ezichanekileyo kakhulu ezisekelwe kumgaqo wokuphazamiseka kokukhanya okumhlophe njenge-microscopy ye-optical enemilinganiselo emithathu, enokufikelela ekulinganisweni kwe-surface topography ngesisombululo se-subnanometer.

I-microscopy ekhethekileyo ye-optical: efana ne-optical nanoscopy echanekileyo yokubeka indawo ye-2nm, efana netekhnoloji ye-MINFLUX, ebonisa ukuba i-microscopy yesisombululo se-nanoscale ingenile ngokusesikweni kwicandelo lophando lwesayensi yobomi.
