Welcome to Particulars

We are experts in designing, building and running Transient Current Technique (TCT) apparatus for studies of various semiconductor devices and materials. We offer optimized components required for building a TCT apparatus as well as assembled setups with software tools for data acquisition and data analysis. A long term experience in using the technique allows us to provide our customers with optimum systems at very affordable price. Different configuration of setups offer optimum time saving solutions for various field of research ranging from educational and classical setups to the most advanced scanning TCT setups with excellent spatial resolution.

What we do

    The products are related to Transient Current Technique:
  • 1. Completely assembled TCT setups for educational use to the high-end applications in science.
