Simple Analytical Model for Optimizing Integrating Sphere Port Sizes
A. M. Bratkovsky
The integrating sphere (IS) is an indispensable tool for measuring transmission and scattering of materials and their colorimetry, as well as other photometric tasks. The accuracy…
Photoluminescence in PbS nanocrystal thin films: Nanocrystal density, film morphology and energy transfer
L. Tsybeskov, M. Alam, S. B. Hafiz +4
We show that photoluminescence properties of PbS nanocrystal thin films are directly related to film morphology and nanocrystal density. In densely packed PbS nanocrystal films, lo…
Plasmon-enhanced second harmonic generation in the laser-irradiated cubic metal nanoparticles
S. V. Fomichev, A. M. Bratkovsky
The plasmon-enhanced second harmonic generation in the subwavelength neutral metal cubic nanoparticles is calculated for the first time in the hydrodynamic and cold plasma approxim…
Sequential Electronic and Structural Transitions in VO2 Observed Using X-ray Absorption Spectromicroscopy
Suhas Kumar, John Paul Strachan, Matthew D. Pickett +3
The popular dual electronic (Mott) and structural (Peierls) transitions in VO2 are explored using x-ray absorption spectromicroscopy with high spatial and spectral resolutions. It…
Perfect memristor: non-volatility, switching and negative differential resistance
Sergey E. Savel'ev, Fabio Marchesoni, Alexander M. Bratkovsky
We propose a simple model of a nanoswitch as a memory resistor. The resistance of the nanoswitch is determined by electron tunneling through a nanoparticle diffusing around one or…
Semiconducting graphene nanomeshes
I. I. Naumov, A. M. Bratkovsky
Symmetry arguments are used to describe all possible two-dimensional periodic corrugations of graphene ("nanomeshes") capable of inducing tangible semiconducting gap. Such nanomesh…
