Magnification effects in scanning tunneling microscopy: the role of surface radicals
Ruslan Zhachuk, Jose Coutinho
Scanning tunneling microscopy (STM) is a fundamental tool for determination of the surface atomic structure. However, the interpretation of high resolution microscopy images is not…
Sub-Band-Gap Absorption Mechanisms Involving Oxygen Vacancies in Hydroxyapatite
Vladimir S. Bystrov, Leon A. Avakyan, Ekaterina V. Paramonova +1
Hydroxyapatite (HAp) is a widely used biomaterial for the preparation of bone and dental implants. Despite the relevance of HAp in medicine, exciting applications involving this ma…
Can we rely on hybrid-DFT energies of solid-state problems with local-DFT geometries?
J. D. Gouveia, J. Coutinho
Hybrid functionals often improve considerably the accuracy of density-functional calculations, in particular of quantities resulting from the band structure. In plane-wave (PW) cal…
Acceptor levels of the carbon vacancy in -SiC: combining Laplace deep level transient spectroscopy with density functional modeling
Ivana Capan, Tomislav Brodar, José Coutinho +3
We provide direct evidence that the broad Z peak, commonly observed by conventional DLTS in as-grown and at high concentrations in radiation damaged -SiC, has two compo…
