HgHfO3
semiconductor· HgHfO3
HgHfO3 is an experimental mixed-metal oxide semiconductor combining mercury and hafnium in a perovskite-like structure. This compound remains largely in the research phase, with potential interest in wide-bandgap semiconductor applications and advanced dielectric systems where hafnium oxides are already established in microelectronics. The mercury incorporation is unusual and represents exploratory work in oxide materials science; practical adoption is limited pending characterization of stability, toxicity concerns, and performance advantages over conventional HfO2-based alternatives.
