Piv nrog cov tshuaj kho qhov muag tsom iav thiab cov tshuab hluav taws xob hluav taws xob, dab tsi txwv qhov kev daws teeb meem ntawm atomic force microscopes?
Lub zog daws teeb meem ntawm cov tshuaj kho qhov muag tsom iav yog txwv los ntawm kev txwv qhov sib txawv ntawm lub teeb, thiab nws qhov kev daws teeb meem tsawg kawg yog ib nrab ntawm nws lub teeb wavelength. Lub zog daws teeb meem ntawm lub tshuab ntsuas hluav taws xob kuj raug txwv los ntawm kev txwv tsis pub dhau, thiab nws qhov kev daws teeb meem tsawg kawg yog ib nrab ntawm electron de Broglie wavelength, yog li lub tshuab hluav taws xob hluav taws xob tuaj yeem ua tiav lub zog daws teeb meem ntau dua li cov khoom siv kho qhov muag.
Lub zog daws teeb meem ntawm lub tshuab tsom iav atomic force feem ntau yog nyob ntawm: qhov loj ntawm qhov kev sojntsuam taub; lub elastic coefficient ntawm micro-cantilever, qhov qis dua elastic coefficient, qhov rhiab heev rau lub tshuab tsom iav atomic force; qhov piv ntawm qhov ntev ntawm lub cantilever mus rau qhov ntev ntawm lub teeb laser; qhov rhiab heev ntawm tus ntes PSD mus rau qhov chaw. Rau ib daim duab nrog ib qho kev daws teeb meem, qhov me dua qhov scanning ntau, qhov zoo dua qhov saum npoo av tau txais.
