NANOSENSORS™ AR5T-NCHR sensors are designed for non-contact mode or Tapping Mode AFM (also known as: attractive or dynamic mode). This sensor type combines high operation stability with outstanding sensitivity and fast scanning ability.
For measurements on samples with sidewall angles approaching 90° NANOSENSORS™ produces specially tailored tips. These tips are FIB (Focused Ion Beam) milled to achieve a high aspect ratio portion at the end of the common silicon tip. This subtractive method of producing the high aspect ratio needle offers the advantage of high lateral stiffness and rigidity of the tip.
On the model AR5T the last 2 µm of the tip are tilted 13° to the center axis of the cantilever. With this feature the tilt angle of the cantilever caused by the mount of the AFM head (commonly 13°) will be compensated. Now, nearly vertical sidewalls can be measured offering a symmetrical scan.
The probe offers unique features: length of the high aspect ratio portion of the tip > 2 µm typical aspect ratio at 2 µm in the order of 7:1 (when viewed from side as well as along cantilever axis) high aspect ratio portion of the tip tilted 13° to the center axis of the cantilever excellent tip radius of curvature highly doped silicon to dissipate static charge high mechanical Q-factor for high sensitivity
