Resonance states in a cylindrical quantum dot with an external magnetic field
(2014)
Bound and resonance states of quantum dots play a significant role in photo-absorption processes. In this work, we analyze a cylindrical quantum dot, its spectrum and, in particular, the behaviour of the lowest resonance ...
Effects of nanoscale spatial inhomogeneity in strongly correlated systems
(2005-03-15)
We calculate ground-state energies and density distributions of Hubbard superlattices characterized by periodic modulations of the on-site interaction and the on-site potential. Both density-matrix renormalization group ...
Thermal behavior for a nanoscale two ferromagnetic phase system based on random anisotropy model
(Elsevier Science, 2010-03)
Advances in theory that explain the magnetic behavior as function of temperature for two phase nanocrystalline soft magnetic materials are presented. The theory developed is based on the well known random anisotropy model, ...
Multiscale fractal descriptors applied to nanoscale images
(SpringerNew York, 2013-07)
This work proposes the application of fractal descriptors to the analysis of nanoscale materials under different experimental conditions. We obtain descriptors for images from the sample applying a multiscale transform to ...
Nanoscale electromechanical properties of CaCu3Ti4O12 ceramics
(American Institute of Physics (AIP), 2011-09-01)
Piezoresponse Force Microscopy (PFM) is used to characterize the nanoscale electromechanical properties of centrosymmetric CaCu3Ti4O12 ceramics with giant dielectric constant. Clear PFM contrast both in vertical (out-of-plane) ...

Influence of the growing parameters on the size distribution of PbTe nanoparticles produced by laser ablation under inert gas atmosphere
(Proceedings of SPIE - The International Society for Optical Engineering Volume 8245, 2012, Article number82450K Synthesis and Photonics of Nanoscale Materials IX; San Francisco, CA; United States; 23 January 2012 through 24 January 2012; Code 89045, 2012-01-23)
We report the fabrication of PbTe quantum dots grown under inert gas (Ar and He) atmosphere by pulsed laser deposition using the second harmonic of a Q-Switched Quantel Nd:YAG laser. For characterization, samples were ...
