Dynamics and fragmentation mechanism of (CH3-C5H4)Pt(CH3)3 on SiO2 Surfaces
K. Muthukumar, Harald O Jeschke, Roser Valenti
The interaction of (CH3-C5H4)Pt(CH3)3 ((methylcyclopentadienyl)trimethylplatinum)) molecules on fully and partially hydroxylated SiO2 surfaces, as well as the dynamics of this inte…
Dynamics of tungsten hexacarbonyl, dicobalt octacarbonyl and their fragments adsorbed on silica surfaces
Kaliappan Muthukumar, Roser Valenti, Harald O. Jeschke
Tungsten and cobalt carbonyls adsorbed on a substrate are typical starting points for the electron beam induced deposition of tungsten or cobalt based metallic nanostructures. We e…
Giant pressure-induced volume collapse in the pyrite mineral MnS2
Simon A. J. Kimber, Ashkan Salamat, Shaun R. Evans +8
Dramatic volume collapses under pressure are fundamental to geochemistry and of increasing importance to fields as diverse as hydrogen storage and high-temperature superconductivit…
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…
Physisorption of an organometallic platinum complex on silica. An ab initio study
Juan Shen, Kaliappan Muthukumar, Harald O. Jeschke +1
The interaction of trimethyl methylcyclopentadienyl platinum (MeCpPtMe3) with a fully hydroxylated SiO2 surface has been explored by means of ab initio calculations. A large slab m…
Interaction of W(CO) with SiO Surfaces -- A Density Functional Study
Kaliappan Muthukumar, Ingo Opahle, Juan Shen +2
The interaction of tungsten hexacarbonyl W(CO) precursor molecules with SiO substrates is investigated by means of density functional theory calculations with and without i…
