ABSTRACT
The radii of the cantilever tips used in this research were determined with the BTR technique to be 79.7 and 60.2 nm for the cantilevers labeled # 1 and # 2, respectively. The values of the tip radii are reasonable despite the possible small error noise artifacts. We estimate the error associated with any noise artifacts in the images to be approximately 8.43 and 6.34 nm for cantilevers #1 and # 2, respectively, and the calculation of this error is discussed later in this paper. Another independent method for determining the tip radius of curvature is still necessary for comparison and validation of the blind tip reconstruction results.
