Study and characterization by magnetophonon resonance of the energy structuring in GaAs/AlAs quantum-wire superlattices
T. Ferrus, B. Goutiers, L. Ressier +4
We present the characterization of the band structure of GaAs/AlAs quantum-wire 1D superlattices performed by magnetophonon resonance with pulsed magnetic fields up to 35 T. The sa…
Optimized minigaps for negative differential resistance creation in strongly delta-doped (1D) superlattices
T. Ferrus, B. Goutiers, L. Ressier +3
The "atomic saw method" uses the passage of dislocations in two-dimensional (2D) quantum-well superlattices to create periodic slipping layers and one-dimensional (1D) quantum wire…
Optical bistability in subwavelength apertures containing nonlinear media
J. A. Porto, L. Martin-Moreno, F. J. Garcia-Vidal
We develop a self-consistent method to study the optical response of metallic gratings with nonlinear media embedded within their subwavelength slits. An optical Kerr nonlinearity…
Resonance shift effects in apertureless scanning near-field optical microscopy
J. A. Porto, P. Johansson, S. P. Apell +1
We develop a theory to study apertureless scanning near-field optical microscopy which takes into account retardation, higher multipoles of the tip, and the multiple scattering bet…
Transmission resonances on metallic gratings with very narrow slits
J. A. Porto, F. J. Garcia-Vidal, J. B. Pendry
In this paper we show how transmission metallic gratings with very narrow and deep enough slits can exhibit transmission resonances for wavelengths larger than the period of the gr…
