Query: Truncated-cone SPM tips for surface-molecules interaction studies   A new tecnique for the production of special shaped SPM tips is reported.
Noble metal coated tips are produced with flat and circular tip front. The
unusual truncated-cone tip shape is obtained by modifying commercial tips. The
diameter of the tip front flat area can be varied continuously in the range
