After obtaining his PhD in the University of the Basque Country (UPV/EHU), Ion Errea worked for two years in the Université Pierre et Marie Curie (UPMC) in Paris, France, as a postdoctoral fellow. The theoretical study of materials from first-principles calculations is his main line of research. He currently continues developing his research at the Donostia International Physics Center (DIPC).

Achieving room temperature superconductivity is among the most pursued but elusive goals of scientists. A paper uploaded to the arXiv in December 2014 claims to have observed superconductivity as high as 190 K in hydrogen sulfide at high pressure, breaking all the records thus far. If this observation is confirmed, cuprates will be knocked from […]
Approximately 90% of world’s electricity is generated in turbines moved by hot steam, which, unfortunately, operate only at 30 to 40 percent efficiency. This means that around two thirds of the total energy input is lost into the environment as waste heat. Thermoelectric materials can convert such waste heat into useful electricity, although they are […]
When in April 1911 Kamerlingh Onnes and coworkers measured that the electrical resistivity of mercury suddenly vanished at 4.2K, they could not believe it. They repeated the experiment several times looking for a short circuit that could explain the weird observation. But any experimental set up was leading to the same result. They had discovered […]
