1. Adhesive stick 6e Tip shape of Tetrahedral tip As can be seen in the left illustration a tetrahedral tip is located at the exact end of the cantilever The finite tip shape will determine the Scan line profile as in the illustrations below The tip profile is symmetric with a half tip angle of 18 degrees macroscopically see left below The side tip profile is asymmetric with a tip angle of 35 degrees Then the cantilever chip is attached to a chip holder in your AFM with an angle about 10 degrees the asymmetry is improved see right below 10 deg 18 deg scan line profile A Sean line profile along B B Tip shape and scan line profile Scan line profile along A A The apex of the tetrahedral tip becomes sharper due to an oxide sharpening process The tip angle around a few hundreds nano meter down from the apex is about 15 to 25 i 15 25 deg 15 25 deg degrees see below Front view Side view Sharpening effect around tip apex When you set your samples to your instrument please consider the unique shape of the tetrahedral tip that is good symmetry when viewing from its front side and choose the direction of the sample When measuring long grooves you can get an idea of what angle of the cut will be quickly by aligning the cantilever along the grooves and scanning across at right angles against grooves see below 6 Information Please contact following if y2.
