Uniaxial stress effects on the structural and electronic properties of BaFe2As2 and CaFe2As2
Milan Tomic, Harald O. Jeschke, Rafael M. Fernandes +1
Starting from the orthorhombic magnetically ordered phase, we investigate the effects of uniaxial tensile and compressive stresses along a, b, and the diagonal a+b directions in Ba…
Absence of metallicity in K-doped picene: Importance of electronic correlations
Andreas Ruff, Michael Sing, Ralph Claessen +4
Potassium-doped picene (Kpicene) has recently been reported to be a superconductor at with critical temperatures up to 18 K. Here we study the electronic structure of K-d…
Unveiling the microscopic nature of correlated organic conductors: the case of kappa-(BEDT-TTF)2Cu[N(CN)2]BrxCl1-x
Johannes Ferber, Kateryna Foyevtsova, Harald O. Jeschke +1
A few organic conductors show a diversity of exciting properties like Mott insulating behaviour, spin liquid, antiferromagnetism, bad metal or unconventional superconductivity cont…
Ab initio study of the two-dimensional metallic state at the surface of SrTiO3: importance of oxygen vacancies
Juan Shen, Hunpyo Lee, Roser Valenti +1
Motivated by recent angle-resolved photoemission spectroscopy (ARPES) observations of a highly metallic two-dimensional electron gas (2DEG) at the (001) vacuum-cleaved surface of S…
Spontaneous Dissociation of Co2(CO)8 and Autocatalytic growth of Co on SiO2 : A Combined Experimental and Theoretical Investigation
Kaliappan Muthukumar, Harald O. Jeschke, Roser Valentí +4
We present experimental results and theoretical simulations of the adsorption behavior of the metal-organic precursor Co2(CO)8 on SiO2 surfaces after application of two different p…
Simulation of structural and electronic properties of amorphous tungsten oxycarbides
Kaliappan Muthukumar, Roser Valenti, Harald O. Jeschke
Electron beam induced deposition with tungsten hexacarbonyl W(CO)6 as precursors leads to granular deposits with varying compositions of tungsten, carbon and oxygen. Depending on t…
