Anisotropic work function of elemental crystals

Ab initio work function of elemental metals.

Surface energies of elemental crystals

The surface energy is a fundamental property of the different facets of a crystal that is crucial to the understanding of various phenomena like surface segregation, roughening, catalytic activity, and the crystal's equilibrium shape. Such surface phenomena are especially important at the nanoscale, where the large surface area to volume ratios lead to properties that are significantly differen...

Ab Initio Study of the Work Functions of Elemental Metal Crystals

THIS thesis is concerned with the theoretical study of the physical characteristics of metallic surfaces. Ab initio quantum calculations are performed to determine the electronic properties of clean elemental metal surfaces, fully accounting for the material’s atomic structure. We aim to understand the atomicscale mechanisms responsible for the dependence of the work function on the surface geo...

Anisotropic magnetic properties of CeAg2Ge2 single crystals

In order to investigate the anisotropic magnetic properties of CeAg2Ge2, we have successfully grown the single crystals, for the first time, by high temperature solution growth (flux) method. We have performed a detailed study of the grown single crystals by measuring their electrical resistivity, magnetic susceptibility, magnetization, specific heat and magnetoresistance. A clear anisotropy an...
