Negative oxygen vacancies in HfO as charge traps in high-k stacks
J. L. Gavartin, D. Munoz Ramo, A. L. Shluger +2
We calculated the optical excitation and thermal ionization energies of oxygen vacancies in m-HfO using atomic basis sets, a non-local density functional and periodic supercell…

The role of nitrogen related defects in high-k dielectric oxides: Density functional studies
J. L. Gavartin, A. S. Foster, G. I. Bersuker +1
Using ab initio density functional total energy and molecular dynamics simulations, we study the effects of various forms of nitrogen post deposition anneal (PDA) on the electric p…
