The physical and chemical properties of materials can be tuned by changing the inter atomic distances in them. In other words, the density defines the properties of materials. The application of pressure is the most direct and straightforward way to change the density of materials. For example,oxygen O2 transforms from gas to liquid, and then to a solid as an applied pressure is increased. Under the compression at around 100 GPa (1 GPa =10000 atmospheric pressure), solid O2 becomes a metal and a superconductor.
Our goal is exploring the novel phenomena of highly compressed materials and revealing the hidden physics. And further more, applying the obtained knowledge, we are trying synthesizing new functional materials.
Using X-ray from a synchrotron radiation, optical experiments, and electrical conducttivity measurements, we are studying the physical and chemical properties of highly compressed materials.
Current target is hydrogen, which is the most abundant element in this universe. Hydrogen is expected to be a metal and a high-temperature superconductor. Hydrogen is also a promising materials which can obtain new functions by doping metal ions.
