About HfKLaO6Ti
HfKLaO6Ti is a complex quaternary oxide that functions as a semiconducting material within the lead-free piezoelectric family. Its metastable nature suggests a unique structural landscape, making it a subject of interest for researchers investigating non-toxic alternatives to traditional ferroelectric ceramics.
Because of its specific elemental composition involving hafnium, lanthanum, and titanium, this compound offers a distinct electronic profile compared to simpler perovskites. It is primarily studied for its potential role in advanced sensing and energy harvesting technologies where lead-based materials are increasingly restricted.
Key Properties
