| Abstract Scope |
Charge order plays an important role in materials properties, such as multiferroicity in electronic device and spintronics, competition/intertwining with superconductivity. Pressure has been used as an efficient fine-tuning tool on electronic and crystal structures, and many advances have been made over the past decades. Being a layered material, it is also interesting to understand how the layers interact with each other with pressure. With aids of advanced synchrotron technologies, in situ high pressure transport measurement, low-temperature and strong magnetic fields, we were able to watch the evolution of structure, CDW, superconductivity and their relationship. Two systems TaSe2 and TaS2 will be discussed in this talk, although similar structures are present at ambient pressure, but their high pressure phase diagrams are quite different regarding their CDW and superconductivity responses with pressure.
Here we present the novel emergent sciences brought about by pressure and look forward more exciting progress. |
