Platinum Silicide Probes Contact Mode
NANOSENSORS™ PtSi-CONT probes are designed for contact mode (repulsive mode) AFM imaging. Furthermore this probe can be used for force-distance spectroscopy or pulsed force mode (PFM) The CONT type is optimized for high sensitivity due a low force constant.
For applications that require a wear resistant and electrically conductive tip we recommend this type. NANOSENSORS PtSi-CONT are suitable for C-AFM, Tunneling AFM (TUNA) and Scanning Capacitance Microscopy (SCM).
The Platinum Silicide coating shows an excellent conductivity (almost approaching metal conductivity). The typical tip radius of curvature is around 25 nm.
The probe offers unique features:
Platinum silicide coating with excellent conductivity and good wear-out behavior
High mechanical Q-factor for high sensitivity
Alignment grooves on backside of silicon holder chip
