Advanced Functional Materials, EarlyView.The chemical composition and band alignment are systematically investigated at the TiO2/InP heterointerface. Thin TiO2 films are deposited by ALD on atomically ordered, P‐terminated p‐InP(100). By combining UPS, XPS, and ab initio molecular dynamics, the atomistic structure and electronic alignment are revealed.

Trapping and guiding surface plasmons in curved graphene landscapes
, 2015 We demonstrate that graphene placed on top of structured substrates offers a novel approach for trapping and guiding surface plasmons. A monolayer graphene with a spatially varying curvature exhibits an effective trapping potential for graphene plasmons ...

Metamaterials for Enhanced Polarization Conversion in Plasmonic Excitation [PDF]
, 2011 Surface plasmons efficient excitation is typically expected to be strongly constrained to transverse magnetic (TM) polarized incidence, as demonstrated so far, due to its intrinsic TM polarization.

Localized surface plasmons of gold nanoparticles
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2022 In this paper, gold nanoparticle far-field and near-field optical responses are studied and simulated numerically. The electromagnetic field was excited by an electric dipole near one end of the nanorod, which is used to model the emission of a quantum ...

Advanced Functional Materials, EarlyView.The SERS spectra of reporter molecules adsorbed on chiral gold nanorods depends on the handedness of circularly polarized light (CPL‐SERS). The bisignate plasmonic CD spectra of chiral nanorods provides wavelength‐dependent CPL‐SERS. Selective discrimination of chiral nanorod handedness and different Raman reporters allow highly sensitive codification ...

Partially coherent surface plasmon modes [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 Elementary long-range plasmon modes are described assuming an exponential dependence of the refractive index in the neighbourhood of the interface dielectric-metal thin film. The study is performed using coupling mode theory. The interference between two
