Photoalignment used to control the orientation of nematic liquid crystals in LCDs usually involves the photochemical modification of the chemical structure of an organic thin film so that an optical and/or steric anisotropy is developed. We now demon... Read More about A new approach to photoalignment: photo-addition to a self-assembled monolayer.

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)

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...
