TL;DR: In this article, the optical excitation and thermal ionization energies of oxygen vacancies in m-HfO2 were calculated using a non-local density functional theory with atomic basis sets and periodic supercell.

TL;DR: In this paper, the authors investigate the characteristics of the defects responsible for leakage current in the SiO2 and SiO 2/HfO2 gate dielectric stacks in a wide temperature range (6 K-400 K).

TL;DR: In this paper, the electronic structure and spectroscopic properties of the oxygen vacancy in different charge states in the monoclinic phase of the material were calculated using density functional theory and a hybrid density functional.

TL;DR: In this paper, an interface dipole model explaining threshold voltage tuning in HfSiON gated n-channel field effect transistors (nFETs) is proposed, which is very similar to the trends in dopant electronegativity (EN) and ionic radius (r) expected for a interfacial dipole mechanism.
