We model the modification in the spontaneous emission (SE) rate of an emitting dipole placed on the surface of a two-dimensional (2D) L3 optical nanocavity using 3D FDTD calculations. We show that by introducing a concave region into the cavity-surfa... Read More about A design for an optical-nanocavity optimized for use with surface-bound light-emitting materials.

Phonon-plasmon coupled-mode lifetime in semiconductors (2008)
Journal Article
Dyson, A., & Ridley, B. K. (2008). Phonon-plasmon coupled-mode lifetime in semiconductors. Journal of applied physics, 103(11), 114507. https://doi.org/10.1063/1.2937918

Raman scattering measurements of the lifetime of hot phonons in GaN show a decrease with increasing electron concentration. Density-dependent lifetimes have also been deduced from noise measurements of AlGaN/GaN channels. We suggest that the results...

The specific rotation of (S)-4-isopropyl-oxazolidin-2-one is extremely solvent dependent. In chloroform it is dextrorotatory {[α] D 26 = + 15.5 (c 5.2, CHCl 3 )}, whereas in ethanol it is levorotatory {[α] D 26 = - 16.1 (c 5.2, EtOH)}. © 2008 Elsevie...

We have mixed nematic light-emitting liquid crystals and incorporated them as insoluble cross-linked polymer networks in a liquid crystal white-light organic light-emitting diode (LC-WOLED). The light emission is not voltage-dependent and polarized w... Read More about White-light OLEDs using liquid crystal polymer networks.

Iterative active-space selection for vibrational configuration interaction calculations using a reduced-coupling VSCF basis (2008)
Journal Article

We adapt a variation-perturbation method to perform vibrational configuration interaction (VCI) calculations on large molecular systems. Starting from a self-consistent vibrational wave function, we use the vibrational configuration interaction with...

We used electron spin resonance (ESR) and electrical conductivity measurements to track the stability of poly(3,4-ethylene dioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) and ethylene glycol (EG)-treated PEDOT:PSS (EG-PEDOT:PSS) films in air. We... Read More about The stability of PEDOT:PSS films monitored by electron spin resonance.

Near-field investigation of porous silicon photoluminescence modification after oxidation in water (2008)
Journal Article

We report on local photo‐induced oxidation of porous silicon in water at room temperature. Starting from a nonluminescent sample, the oxidation process induces luminescence which was found to first increase and then decrease as a function of the oxid...

In this paper, we study the performances of nanosensors based on Localized Surface Plasmon Resonance in the context of biological sensing. We demonstrate the sensitivity and the selectivity of our designed nanosensors by studying the influence of the...

The polymer poly(9,9-dioctylfluorene) (PF8) can be driven into a morphological form termed the β-phase that has enhanced planarity and increased structural rigidity. We show that the β-phase can be generated in two different fluorene oligomers; a flu... Read More about Observation of the β-phase in two short-chain oligofluorenes.
