hafnium (Hf), chemical element ( atomic number 72), metal of Group 4 (IVb) of the periodic table. It is a ductile metal with a brilliant silvery lustre. The Dutch physicist Dirk Coster and the Hungarian Swedish chemist George Charles von Hevesy discovered (1923) hafnium in Norwegian and Greenland zircons by analyzing their X-ray spectra.
Section snippets Methods. We simulated the electronic structure of monoclinic (m-) and orthorhombic (o-) HfO 2 as the most stable crystalline hafnia phase [3]. The Quantum-ESPRESSO software for ab initio simulations [4] was used. The simulations were based on the density functional theory (DFT) within the plane-wave as a basis set and …
