A series of Tapping Mode Scanning Force Microscopy Images of Si(001) surfaces. Image sizes are: 0x0, 1x1nm, 3x3nm, 10x10nm, 30x30nm, 100x100nm, 300x300nm, 1x1um, 3x3um, 10x10um, 30x30um, 100x100um. The Z-scale is 1nm for all but the last two images. The scale for 30x30um is 10nm and for 100x100um is 100nm. This set is taken for use as base line in surface roughness spectroscopy. Questions invited.
