An atomic-level rendering of the material known as hafnium oxide, which consists of one hafnium atom (white) for every two oxygen (red). Bucking years of conventional wisdom, Husker researchers have shown that the material’s most technologically appealing property can emerge from unexpected conditions.

Jeffrey Shield, department chair and Robert W. Brightfelt Professor of Mechanical and Materials Engineering, is among a team of University of Nebraska-Lincoln materials researchers who have shown that larger grains of hafnium oxide produce higher-quality, more relaiable ferroelectricity, contrary to long-held notions about the material. Their study was recently published in the journal New Materials.
