PA01

Product Description:

Sample for characterization of tip shape with hard sharp pyramidal nanostructures. The pyramids are triangular with base length in the range 50 – 100 nm and height 50 – 150 nm. The radius of curvature of the sharpest edges is below 5 nm.

The structures of the PA01 are covered by a highly wear-resistant layer.

• pyramid base 50 - 100 nm
• pyramid height 50 - 150 nm
• smallest edge radii < 5 nm
• active area 5 x 5 mm
• chip dimensions 5 x 5 x 0.7 mm
• available mounted on 12 mm metal plate (PA01) or unmounted (PA01/NM) 

Application

The exact shape of the scanning probe tip is very important for obtaining AFM images of high quality and accuracy. As new AFM tips with nanometer radii of curvature become widespread, periodic structures that have surface features of similar or greater sharpness should be used to estimate the parameters of the tip. An AFM image of the PA structures is shown above. The AFM image is obtained using an OPUS 240AC-NA probe.
