1. Broad-Band Spectroscopy

We are able to perform dielectric and transport studies utilizing a large variety of techniques which continuously cover the frequency range from 3µHz up to 360THz.

2. Nonlinear Spectroscopy

In broadband dielectric spectroscopy, usually relatively low voltages of up to several volts are applied to the samples. Thus, these measurements are performed in the linear regime of the P(E) (polarization vs. field) curve. In contrast, applying higher voltages (up to 2000V in our lab) can lead to pronounced nonlinear effects, which can provide valuable additional information. A variety of field-dependent and pyroelectric measurements can be performed in our group.
