HF2PLL for KPFM Applications

on 14.04.2013 at 13:17 by andreas
Kelvin Probe Force Microscopy (KPFM) is a scanning technique that allows the detection of a electrostatic potential distribution of a surface. The HF2PLL supports several variants of KPFM, some of them are mentioned in this post. Amplitude modulated KPFM (AM-KPFM) […]

Using TipProtect to extend AFM tip life expectancy

on 03.12.2012 at 14:51 by andreas
Using a Zurich Instruments Lock-In amplifier, you are enabled to perform a multitude of AFM measurement modes. Particularly interesting is NC-AFM operation which makes use of the built-in PLL capability. Earlier, a user could easily crash his tip into a […]
