Electronic Properties of Elements at Mbar Pressure and Low Temperature

Abstract

In this article, our experimental investigation to study electronic properties of elements under Mbar pressure and low temperature conditions are reviewed. So-called “treasure hunting” has been continued after the finding of superconductivity in elemental mercury at 1911. But complete understanding of the mechanism of appearance of superconductivity is not uncovered yet. Pressure can change the structural distance of atom and the electronic properties, then could be one of the most powerful tool for uncover it. The number of superconducting elements actually increased up to 53 under pressure from 30 at ambient pressure. The aim is to share our idea and experimental struggle process behind the papers already published.
