Relative stability of -SiC surface terminations and formation of graphene overlayers by Si evaporation
Jochen Rohrer, Eleni Ziambaras, Per Hyldgaard
We present density functional theory (DFT) calculations for 6H-SiC surfaces with different surface stackings and terminations. We compare the relative stability of differ…
Potassium intercalation in graphite: A van der Waals density-functional study
Eleni Ziambaras, Jesper Kleis, Elsebeth Schroder +1
Potassium intercalation in graphite is investigated by first-principles theory. The bonding in the potassium-graphite compound is reasonably well accounted for by traditional semil…
Phonon Knudsen flow in nanostructured semiconductor systems
Eleni Ziambaras, Per Hyldgaard
We determine the size effect on the lattice thermal conductivity of nanoscale wire and multilayer structures formed in and by some typical semiconductor materials, using the Boltzm…
Thermal transport in SiC nanostructures
Eleni Ziambaras, Per Hyldgaard
SiC is a robust semiconductor material considered ideal for high-power application due to its material stability and large bulk thermal conductivity defined by the very fast phonon…
Theory for structure and bulk-modulus determination
Eleni Ziambaras, Elsebeth Schroder
A new method for direct evaluation of both crystalline structure, bulk modulus B_0, and bulk-modulus pressure derivative B'_0 of solid materials with complex crystal structures is…
