Growth mechanisms of GaN/GaAs nanostructures by droplet epitaxy explained by complementary experiments and simulations
Guy Tsamo, Alla G. Nastovjak, Nataliya L. Shwartz +9
In this work, we present conception and study of gallium nitride (GaN) nanostructures on a gallium arsenide (GaAs) substrate with (111)A orientation. The nanostructures were design…
Exponent equality for capture-zone scaling in island nucleation: Theory and application to organic films
Alberto Pimpinelli, Levent Tumbek, Adolf Winkler
It is known in thin-film deposition that the density of nucleated clusters varies with the deposition rate as a power law, . The exponent is a function of t…
Effect of impurities on pentacene island nucleation
B. R. Conrad, Elba Gomar-Nadal, W. G. Cullen +3
Pentacenequinone (PnQ) impurities have been introduced into a pentacene source material in a controlled manner to quantify the relative effects of the impurity content on grain bou…
Relaxation of Terrace-width Distributions: Physical Information from Fokker-Planck Time
Ajmi BH. Hamouda, Alberto Pimpinelli, T. L. Einstein
Recently some of us have constructed a Fokker-Planck formalism to describe the equilibration of the terrace-width distribution of a vicinal surface from an arbitrary initial config…
Scaling properties of step bunches induced by sublimation and related mechanisms: A unified perspective
Joachim Krug, Vesselin Tonchev, Stoyan Stoyanov +1
This work provides a ground for a quantitative interpretation of experiments on step bunching during sublimation of crystals with a pronounced Ehrlich-Schwoebel (ES) barrier in the…
Changing shapes in the nanoworld
Nicolas Combe, Pablo Jensen, Alberto Pimpinelli
What are the mechanisms leading to the shape relaxation of three dimensional crystallites ? Kinetic Monte Carlo simulations of fcc clusters show that the usual theories of equilibr…
