چکیده
Strong resonant enhancement of Raman scattering on photonic resonance was observed in GaAsP semiconductor nanowires. The allowed for detailed studies the surface phonon polariton (SPhP) peak individual In particular, first time, effect nanowire cross section shape SPhP properties has been investigated. It found that flattening induces a strong polarisation and spectral shift SPhPs supported by such nanowire. assisting numerical simulations to link induced splitting HE11 mode flattened also theoretically reproduced elliptical approximation section. obtained results pave ground engineering response accurate control applications utilising morphology.

Raman scattering as a probe of phonon confinement and surface optical modes in semiconducting nanowires
Raman scattering is shown to be an effective probe of optical and surface optical phonons in highly crystalline semiconducting nanowires (SNWs). We show that the confinement model of Richter et al. well describes the nanowire diameter dependence of the asymmetric broadening of the onephonon band in Si nanowires observed at ∼ 520 cm−1. We also show that the use of high laser flux (∼ 0.1 mW/μm2) ...
متن کاملRaman scattering due to disorder-induced polaritons
The selection rules for dipole and Raman activity can be relaxed due to local distortion of a crystalline structure. In this situation a dipole-inactive mode can become simultaneously active in Raman scattering and in dipole interaction with the electromagnetic field. The later interaction results in disorder-induced polaritons, which could be observed in first-order Raman spectra. We calculate...

Highly porous bimetallic nanowires manufactured via a simple galvanic reaction have demonstrated superior activity in surface-enhanced Raman scattering, allowing ultrasensitive chemical detections on isolated porous nanowires in comparison to pristine silver nanowires.
متن کاملTheory of Nonlinear s-Polarized Phonon-Polaritons in Multilayered Structures
A theory is presented for the dispersion relations of the nonlinear phonon-polaritons arising when phonons are coupled to the electromagnetic waves in multilayered structures of nonlinear materials. The calculations are applied to a multilayered structure consisting of a thin film surrounded by semi-infinite bounding media where each layer may have a frequency dependent dielectric function and ...
متن کاملChiral surface plasmon polaritons on metallic nanowires.
Chiral surface plasmon polaritons (SPPs) can be generated by linearly polarized light incident at the end of a nanowire, exciting a coherent superposition of three specific nanowire waveguide modes. Images of chiral SPPs on individual nanowires obtained from quantum dot fluorescence excited by the SPP evanescent field reveal the chirality predicted in our theoretical model. The handedness and s...
