Extraordinary electron transmission through a periodic array of quantum dots
L. S. Petrosyan, A. S. Kirakosyan, T. V. Shahbazyan
We study electron transmission through a periodic array of quantum dots (QD) sandwiched between doped semiconductor leads. When the Fermi wavelength of tunneling electron exceeds t…
Surface plasmon lifetime in metal nanoshells
A. S. Kirakosyan, M. I. Stockman, T. V. Shahbazyan
The lifetime of localized surface plasmon plays an important role in many aspects of plasmonics and its applications. In small metal nanostructures, the dominant mechanism restrict…
Ultrafast dynamics of surface electromagnetic waves in nanohole array on metallic film
A. S. Kirakosyan, M. Tong, T. V. Shahbazyan +1
We study the ultrafast dynamics of surface electromagnetic waves photogenerated on aluminum film perforated with subwavelength holes array by means of transient photomodulation wit…
Vibrational modes of metal nanoshells and bimetallic core-shell nanoparticles
Arman S. Kirakosyan, Tigran V. Shahbazyan
We study theoretically spectrum of radial vibrational modes in composite metal nanostructures such as bimetallic core-shell particles and metal nanoshells with dielectric core in a…
Ultrafast response of surface electromagnetic waves in an aluminum film perforated with subwavelength hole arrays
M. Tong, A. S. Kirakosyan, T. V. Shahbazyan +1
The ultrafast dynamics of surface electromagnetic waves photogenerated on aluminum film perforated with subwavelength holes array was studied in the visible spectral range by the t…
Coherent acoustic vibration of metal nanoshells
C. Guillon, P. Langot, N. Del Fatti +5
Using time-resolved pump-probe spectroscopy we have performed the first investigation of the vibrational modes of gold nanoshells. The fundamental isotropic mode launched by a femt…
