Studies of Multiple Metal Doped Silicon Clusters and Design of Novel Materials Based on Clusters Containing Silicon and Germanium. KU Leuven
Geometric, Electronic and Magnetic Properties of Transition Metal Doped Silicon Clusters, and Development of a Magnetic Deflection Setup KU Leuven
The aim of the work presented in this thesis is to provide deeper understanding on the geometric, electronic, and magnetic properties of gas phase clusters as a function of size and composition using a combination of the spectroscopic techniques and density functional theory (DFT) calculations. The thesis is divided into four parts. A review of recent research on the structural identification of doped silicon clusters is given in Part I. In ...
Spin transport through metal-encapsulated silicon clusters KU Leuven
In this PhD project, we will produce beams of metal encapsulated silicon clusters in the gas phase, size-select the most stable clusters, and deposit them on flat surfaces. The morphology, electronic properties and spin ordering of assemblies of those endohedrally doped silicon cage clusters on the surfaces will be studied with low-temperature ultra-high vacuum scanning tunneling microscopy techniques and compared with the intrinsic ...
Excited states, optical spectra, and decay dynamics of small coinage metal clusters KU Leuven
The main ambition of the cluster science research field is to understand how matter is built up from an atom over clusters and nanoparticles to larger systems including bulk. Central knowledge in the field is that properties of clusters are strongly size dependent and that zero dimensional quantum confinement determines their physical and chemical properties in a non-scalable way. So far, very little experimental and theoretical information ...
Computational Studies of Small Boron Based Clusters KU Leuven
From geometrical features of the global minima, a growth mechanism for each series of the BnX clusters was established. The fundamental featuressuch as chemical bonding, electronic distribution, aromaticity, were probed using the analyses of canonical molecular orbital (CMO) in combination with other indices obtained from the electron localization function(ELF), nuclear independent chemical shift (NICS) etc
Quantitatively, ...
Metal-doped carbon clusters as model systems for the chemical storage of hydrogen KU Leuven
Correlating structure and properties of novel functional molecular metal clusters deposited on surfaces and embedded in 3D matrices KU Leuven
Molecular metal clusters (MMCs) are metal aggregates below 20 atoms presenting a molecule-like behavior that confer them very promising functionalities for applications in diverse fields such as photonics, catalysis, and spintronics. Although a new class of high performance materials based on (multi)functional MMCs is rapidly growing, fundamental understanding of their (electronic) structure and their properties is today very often lacking, ...
Electrodeposited silicon films on nanoporous metals for Li-ion battery anodes: linking nanoscale structure to macroscale performance Hasselt University
Africa’s Silicon Landscapes: negotiating Information and Communication Technology in Lagos KU Leuven
To improve our understanding of the interactions and negotiations between society and Information and Communication Technologies (ICTs) in sub-Saharan African ‘silicon places’, LAGOSTECH will investigate the experiences of technology in and the digital creativity emanating from two technological nodes (Yaba and Talent City) in Lagos. Nigeria is home to the largest number of tech hubs in Africa, but paradoxically is also where silicon places ...
