High pressure structural and transport properties study for Oxyselenides BiCuSeO

【摘要】：正Oxyselenides compounds Bi Cu Se O(BCSO)has recently been reported as one of the best oxide-based thermoelectric(TE)materials with the peak ZT value of 1.4.Various endeavors have been carried out for optimizing its TE properties,including single/double doping,vacancies-introducing,and texturing and so on.All the investigations are on the basis of ambient pressure.As known,matter shows many
