Category:
Pyramidal silicon etched probes are characterized by high tip sharpness and narrow resonance peaks, making them very suitable for topography imaging in dynamic AFM modes and compositional mapping. These probes are available in a wide range of resonance frequencies and spring constants.
Tip properties:
Tip radius ......................8 nm
Tip material ................silicon
Backside coating:
Al BS ..............................Al 30 nm
no Al ..............................none
Cr-Au BS .......................Au 30 nm on Cr 20 nm sublayer
