Application of perturbation theory to finding vibrational frequencies of a spheroid
M. O. Nestoklon, L. Saviot, S. V. Goupalov
We apply perturbation theory of boundary conditions, originally developed by A.B. Migdal and independently by S.A. Moszkowski for deformed atomic nuclei, to finding eigenfrequencie…
Confined acoustic phonons in CsPbI3 nanocrystals explored by resonant Raman scattering on excitons
Carolin Harkort, Ina V. Kalitukha, Nataliia E. Kopteva +8
Optical properties of the lead halide perovskites nanocrystals are controlled by confined excitons and rich spectrum of confined acoustic and optical phonons. We study experimental…
Spectroscopic, Structural, and Theoretical Studies of Halide Complexes with a Urea-based Tripodal Receptor
Avijit Pramanik, Douglas R. Powell, Bryan M. Wong +1
A urea-based tripodal receptor L substituted with p-cyanophenyl groups has been studied for halide anions by H NMR spectroscopy, density functional theory (DFT) calculations an…
Thioglycolic acid on the gold (111) surface and Raman vibrational spectra
Jian-Ge Zhou, Quinton L. Williams, Ruqian Wu
The interaction of thioglycolic acid with the Au(111) surface is investigaged, and it is found that at the low coverage the molecule lies down on the substrate. If the mercaptan-hy…
How does an external electrical field affect adsorption patterns of thiol and thiolate on the gold substrate ?
Jian-Ge Zhou, Quinton L. Williams
The responsive behavior of methanethiol and methylthiolate molecules on the Au(111) surface with an applied electrical potential is studied, and it is shown how the sulfur adsorpti…
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…
Carrier relaxation in Si/SiO quantum dots
A. A. Prokofiev, S. V. Goupalov, A. S. Moskalenko +2
Carrier relaxation due to both optical and nonradiative intraband transitions in silicon quantum dots in SiO has been considered. Interaction of confined holes with optical pho…
Cooperative emission of light by an ensemble of dipoles near a metal nanostucture: The plasmonic Dicke effect
Vitaliy N. Pustovit, Tigran V. Shahbazyan
We identify a new mechanism for cooperative emission of light by an ensemble of N dipoles near a metal nanostructure supporting a surface plasmon.The cross-talk between emitters du…
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…
The CH3SH molecule deposited on Cu(111) and deprotonation
Jian-Ge Zhou, Quinton L. Williams, Frank Hagelberg
We demonstrate for the first time that when a methanethiol adsorbed on the regular Cu(111) surface, the dissociative structure is thermodynamically more stable than the intact one.…
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…
Headgroup dimerization in methanethiol monolayers on the Au(111) surface: a density functional theory study
Jian-Ge Zhou, Quinton L. Williams, Frank Hagelberg
A long-standing controversy related to the dimer pattern formed by S atoms in methanethiol () on the Au(111) surface has been resolved using density functional theory. Fo…
Do methanethiol adsorbates on the Au(111) surface dissociate?
Jian-Ge Zhou, Frank Hagelberg
The interaction of methanethiol molecules CHSH with the Au(111) surface is investigated, and it is found for the first time that the S-H bond remains intact when the methanet…
Coverage dependence of the 1-propanol adsorption on the Si(001) surface and fragmentation dynamics
Jian-Ge Zhou, Frank Hagelberg, Chuanyun Xiao
The geometric, electronic, energetic, and dynamic properties of 1-propanol adsorbed on the Si(001)-2x1 surface are studied from first principles by use of a slab approach. The 1-pr…
From Bubble to Skyrmion: Dynamic Transformation Mediated by a Strong Magnetic Tip
A. S. Kirakosyan, V. L. Pokrovsky
Skyrmions in thin metallic ferromagnetic films are stable due to competition between the RKKY interaction and uniaxial magnetic anisotropy. We mimic the RKKY interaction by the nex…
