Controlling the coexistence of structural phases and the optical properties of gallium nanoparticles with optical excitation
K. F. MacDonald, V. A. Fedotov, S. Pochon +3
We have observed reversible structural transformations, induced by optical excitation at 1.55 micrometer, between the beta, gamma and liquid phases of gallium in self-assembled gal…

Phase coexistence in Gallium nanoparticles controlled by electron excitation
S. Pochon, K. F. MacDonald, R. J. Knize +1
In Gallium nanoparticles of 100 nm in diameter grown on the tip of an optical fiber from an atomic beam we observed equilibrium coexistence of gamma, beta and liquid structural pha…

Gallium nanoparticles grow where light is
K. F. MacDonald, W. S. Brocklesby, V. I. Emelyanov +5
The study of metallic nanoparticles has a long tradition in linear and nonlinear optics [1], with current emphasis on the ultrafast dynamics, size, shape and collective effects in…
