Research enters a new phase

New research has indicated that it is possible to measure the short-term phase-coherence properties of high-Tc materials. The researchers were able to measure the frequency-dependent conductivity, which links the alternating currents flowing in the superconductor with an applied alternating electric field. The coherent time-domain spectroscopy technique developed in earlier research has now been made into a strong tool for investigating the frequency range of 100 GHz to 600 GHz.
