I-atomic force afm microscope
I-Atomic Force Microscope (AFM), isixhobo sokuhlalutya esinokusetyenziselwa ukufunda ubume bomphezulu bezinto eziqinileyo, kubandakanywa nezithinteli.Iphonononga ubume bomphezulu kunye neepropathi zento ngokufumanisa unxibelelwano olubuthathaka kakhulu lwe-interatomic phakathi komphezulu wesampulu eza kuvavanywa kunye ne-micro-force element enovakalelo.Kuya kuba isibini amandla abuthathaka kakhulu olubuthathaka kakhulu isiphelo micro-cantilever esisigxina, elinye isiphelo incam encinane kufutshane isampuli, ngoko iya kusebenzisana nayo, amandla uya kwenza deformation micro-cantilever okanye utshintsho intshukumo karhulumente.Xa uhlola isampuli, inzwa ingasetyenziselwa ukufumanisa olu tshintsho, sinokufumana ukuhanjiswa kolwazi lwamandla, ukuze sifumane i-morphology yolwazi lwe-nano-resolution kunye nolwazi oluphezulu.
★ Iprobe yokuskena edityanisiweyo kunye nestag yesampulu iphucule isakhono sokuchasana nokuphazamiseka.
★ Ukuchaneka kwelaser kunye nesixhobo sokumisa iprobe senza ukutshintsha iprobe kunye nokulungelelanisa indawo kube lula kwaye kulula.
★ Ngokusebenzisa isampuli yovavanyo olusondela ngendlela,inaliti inokuba ne-perpendicular kwisampulu yokuskena.
★ Ulawulo oluzenzekelayo lwepulse motor drive probe isondela ngokuthe nkqo, ukufikelela kwindawo echanekileyo yendawo yokuskena.
★ iSampuli yokuskena indawo enomdla inokushukunyiswa ngokukhululekileyo ngokusebenzisa uyilo lwesampulu echanekileyo ephezulu yesixhobo esiphathwayo.
★ Inkqubo yoqwalaselo yeCCD enendawo yokubona ifezekisa uqwalaselo lwexesha lokwenyani kunye nokubekwa kwendawo yesampulu yeprobe yokuskena.
★ Uyilo lwenkqubo yolawulo lwe-elektroniki yohlengahlengiso luququzelele ukugcinwa kunye nokuphuculwa okuqhubekayo kweesekethe.
★ Ukudityaniswa kwesekethe yolawulo lwemowudi yokuskena, sebenzisana nenkqubo yesoftware.
★ Ukunqunyanyiswa kwentwasahlobo ekulula kunye nokusebenzayo ukomeleza isakhono sokuchasana nokuphazamiseka.
