Alumnus/Alumna: Organic Metals: Superconductivity and Correlated Electron Systems

Dieter Andres was member of the Gross group at WMI as Ph.D. student between 2000 and 2005.

Ph.D. Thesis: Effects of high magnetic fields and hydrostatic pressure on the low temperature density wave state of the organic metal alpha-(BEDT-TTF)₂KHg(SCN)₄ (2005)

In his Ph.D. thesis, Dieter Andres was studying the physical properties of organic metals. His results supported the initial suggestion that below 8 K there exists a charge-density wave in the layered organic compound alpha-(BEDT-TTF)₂KHg(SCN)₄. He showed that the phase transition becomes suppressed under hydrostatic pressure, but can be re-established by applying a magnetic field. At certain experimental conditions he found even successive magnetic-field-induced first order transitions between different charge-density waves realized. These were the first experimental evidences for such magnetic field effects in a charge-density wave system. In addition, he found a superconducting state under pressure, which even coexists with the charge-density wave in a certain pressure range.

After finishing his Ph.D. thesis, he left WMI to start a career in industry with attocube systems AG.
