I took lots of images today but not qualified..



0.2um 0.2s 128 1nA 50mv 0.2 0.2 128 1 50 Until this image, the tip was okay.. the tip is little bit picky 0.12 0.2 128 1 50

77nm 0.2 128 1 50

I changed the tip from this image

91nm 0.2 128 1 50 I was expecting those dots might be the molecules but after zooming in I could say those were not 51nm 0.2 128 1 50

I also took lots of images today.. image width 0.2um Time line 0.2 points line 128 set point 1nA tip voltage 50mV

moved the area and reapproaching

Moved the spot and reapproaching 0.2nm 0.2 128 " " Moved the spot and reapproaching

92nm 0.2 128 " "

zoomed in one flat spot and found white dots that seemed a cluster of molecules.. This white dot might be clusters of molecules..or not.. I am not sure..but what I am sure is that is not one molecule.. That spot is too big to be a molecule..
