PointProbe® Plus Non-Contact / Tapping Mode - High Resonance Frequency - Au coating
The Point Probe® Plus (PPP) combines the well-known features of the proven PointProbe® series such as high application versatility and compatibility with most commercial SPMs with a more reproducible AFM tip radius as well as a more defined AFM tip shape. The minimized variation in AFM tip shape provides more reproducible images.
NANOSENSORS™ PPP-NCHAu AFM probes are designed for non-contact mode or tapping mode AFM (also known as: attractive or dynamic mode). This sensor type combines high electrical conductivity with outstanding sensitivity and fast scanning ability.
The AFM probe offers unique features:
- metallic conductivity of the AFM tip
- AFM tip height 10 - 15 µm
- Au coating on detector side of AFM cantilever
- chemically inert
A metallic layer (Au) is coated on both sides of the AFM cantilever. The tip side coating enhances the conductivity of the AFM tip and allows electrical contacts - the typical AFM tip radius of curvature is less than 50nm. The detector side coating enhances the reflectivity of the laser beam by a factor of 2.5 and prevents light from interfering within the AFM cantilever. The coating process is optimized for stress compensation. The bending of the AFM cantilever due to stress is less than 3.5% of the AFM cantilever length.
Please note: Wear at the AFM tip can occur if operating in contact-, friction- or force modulation mode.
This AFM probe features alignment grooves on the back side of the holder chip. These grooves fit to the NANOSENSORS Alignment Chip.
