TRMC

In Delft we have already for more than 25 years experience in performing electrodeless time-resolved microwave conductivity measurements. Initially focussing on powders and solutions using a so called van der Graaff accelerator to induce charge carriers; Later on a set-up was developed for measuring changes in conductivity on pulsed optical excitation. Below is an overview of the essentials parts of our microwave system including a short description. More information can be found here and here.
