Thickness-dependent spontaneous dewetting morphology of ultrathin Ag films
H. Krishna, R. Sachan, J. Strader +3
We show here that the morphological pathway of spontaneous dewetting of ultrathin Ag films on SiO2 under nanosecond laser melting is found to be film thickness dependent. For films…
Self-organized synthesis of patterned magnetic nanostructures with in-plane and perpendicular to the plane magnetization
H. Krishna, A. K. Gangopadhyay, J. Strader +1
Patterned arrays of ferromagnetic nanoparticles of Co, Ni, and Fe_{\text{50}} Co_{\text{50}} have been synthesized from their ultrathin metal films on SiO_{\text{2}} substrate by n…
Thermodynamic approach to the dewetting instability in ultrathin films
N. Shirato, H. Krishna, R. Kalyanaraman
The fluid dynamics of the classical dewetting instability in ultrathin films is a non-linear process. However, the physical manifestation of the instability in terms of characteris…
A compound figure of merit for photonic applications of metal nanocomposites
Hernando Garcia, Hare Krishna, Ramki Kalyanaraman
Selecting nanocomposites for photonic switching applications requires optimizing their thermal, nonlinear and two-photon absorption characteristics. We simplify this step by defini…
