Improper ferroelectricity in hexagonal tungsten bronzes

We address the detailed atomistic mechanism of ferroelectricity in a new family of oxides typified by the composition CsNbW2O9. Contrary to the mechanism in most ferroelectrics,...本研究针对以CsNbW2O9为典型组分的新型氧化物家族的铁电性详细原子尺度机制展开探讨。与绝大多数铁电体的作用机制相悖，……
