The ultra-compact TRIBUS is a universal SPM for a wide variety of applications. Whether for SPM-spectroscopy, surface imaging, or manipulation of nanoparticles, for experiments at elevated temperatures or at the milli-Kelvin scale, in high magnetic fields or in spatially tight environments, the TRIBUS SPM is the ideal choice whenever highest resolution, accuracy and flexibility are required.
The TRIBUS SPM head was designed for high resolution STM, QPlus®-AFM, and spectroscopy experiments in a temperature range between mK and up to 420 K.
Due to its small footprint, non-magnetic materials, and compatibility with a wide temperature range the integration into almost every UHV environment is possible.
Special attention was paid to the selection and pre-characterisation of materials for the TRIBUS head. As a result, it has a minimal thermal drift and optimum stiff ness, which yields excellent stability in the SPM.
Aspects such as 3D coarse motors with independent and orthogonal axes, and easy and safe in-situ tip and sample exchange, facilitate ease of daily work. Additional features such as multiple electrical sample contacts and optical access ports extend the possible applications beyond standard SPM measurements.
There are two variants of the TRIBUS: TRIBUS Ultra for temperatures down to mK range and high magnetic fields (> 2T), and TRIBUS for temperatures above 1.1 K and magnetic fields of < 2T.
