Monocrystalline lattice matched Er(0.6 at. %): (Gd, LU)(2)O-3 films with nearly atomically flat surfaces and thicknesses up to 3 Am have been grown on Y2O3 substrates using pulsed laser deposition. The emission cross sections were comparable with the ones ...
The electrons of the surface states on the (I 11) surfaces of the noble metals An, Ag, and Cu form a quasi-two-dimensional (2D) free electron gas which is confined to the first few atomic layers at the crystal surface. They are scattered by the potential a ...
We present a detailed study of GaN pillar arrays by atomic force microscopy (AFM), Raman spectroscopy, and photoluminescence (PL) spectroscopy. AFM is used to characterize the shape of the GaN pillars and revealed a large roughness of etched pillar surface ...
Two selected examples have been chosen to illustrate the ability of non-resonant Raman scattering to probe phonons in hexagonal GaN-AlN artificial structures. The angular dispersion of polar phonons is investigated in a long period GaN-AlN superlattice and ...
Mode-selective surface-enhanced Raman spectroscopy (SERS) is demonstrated using plasmonic dipole antennas fabricated with electron beam lithography. An similar to 10x change of the relative enhancement between two different Raman modes is observed when the ...
Scattering processes in an optical microcavity are investigated for the case of silicon nanocrystals embedded in an ultra-high-Q toroid microcavity. Using a novel measurement technique based on the observable mode splitting, we demonstrate that light scatt ...
The dependence of stimulated polariton-polariton scattering in InGaAs/GaAs/AlGaAs microcavities on pump power, angle, and energy is investigated. We show that contrary to much previous belief there is no "magic angle" for stimulated scattering under contin ...
We report on the results obtained during the commissioning phase of the volume photoemission (VOLPE) project, now operational at ESRF. Test experiments were performed on noble metals and highly correlated systems, analyzing photoelectrons with kinetic ener ...
We show that stimulated polariton scattering in a semiconductor microcavity is observable over a wide range of laser pump angles. The ratio of idler to signal beams is found to vary strongly with angle, consistent with the expected variation of the photon ...
An 8 times 16 array of sensing micro-sites employs a fully-electrical label-free technique for DNA recognition using capacitance measurement and is fabricated in 0.5mum CMOS with added noble metal. Repeatability and parallel detection capability have been ...
