Nonlinear effects in synthetic frequency dimension created by electro-optical modulation of a ring resonator

Tobias Kippenberg, Alexey Tikan, Aleksandr Tusnin

We numerically investigate the nonlinear dynamics of an optical resonator with electro-optical modulation. In this system we discover chimera states and their transition into new stable states with increasing modulation amplitude. Bifurcation analysis reve ...

Impact of alloy disorder on Auger recombination in single InGaN/GaN core-shell microrods

Benoît Marie Joseph Deveaud, Gwénolé Jean Jacopin, Georg Rossbach, Wei Liu

We study the influence of local inhomogeneities on carrier recombination dynamics in single InGaN/GaN core-shell microrods (MRs) by means of time-resolved microphotoluminescence (TRPL) at 10 K. At low carrier density (similar to 10(11) cm(-2)), the carrier ...

Scanning thermal probe microscope method for the determination of thermal diffusivity of nanocomposite thin films

Jürgen Brugger

A commercial scanning thermal microscope has been upgraded to facilitate its use in estimating the radial thermal diffusivity of thin films close to room temperature. The modified setup includes a microcontroller driven microhotplate coupled with a Bluetoo ...

Thermal diffusivity measurements of templated nanocomposite using infrared thermography

Helmuth Berger, Arnaud Magrez, Philippe Bugnon

Electrodeposited bismuth telluride (Bi2Te3) nanowires using anodic alumina (AAO) templates show anisotropic thermal properties in a direction parallel and perpendicular to the nanowire/nanochannel axis. The present study reports thermal diffusivity measure ...

NanoSIMS: Technical Aspects and Applications in Cosmochemistry and Biological Geochemistry

Anders Meibom, Shirit Cohen, Stéphanie Kéren Cohen

The NanoSIMS ion probe is a new-generation SIMS instrument, characterised by superior spatial resolution, high sensitivity and multi-collection capability. Isotope studies of certain elements can be conducted with 50-100nm resolution, making the NanoSIMS a ...
