Saddle point mirror descent algorithm for the robust PageRank problem

Autor: A. V. Nazin, A. A. Tremba

Publikováno v: Automation and Remote Control. 77:1403-1418

In order to solve robust PageRank problem a saddle-point Mirror Descent algorithm for solving convex-concave optimization problems is enhanced and studied. The algorithm is based on two proxy functions, which use specificities of value sets to be opt

Publikováno v: Physical Chemistry Chemical Physics. 18:4842-4849

Charge transport in polymer- and oligomer-based semiconductor materials depends strongly on the structural ordering of the constituent molecules. Variations in molecular conformations influence the electronic structures of polymers and oligomers, and

Recent studies have shown the presence of an amorphous surface layer in nominally crystalline silicon nanocrystals (SiNCs) produced by some of the most common synthetic techniques. The amorphous surface layer can serve as a source of deep charge trap

Coverage-Dependent Self-Assembly Regimes of Alkyl-Substituted Thiophene Oligomers on Au(111): Scanning Tunneling Microscopy and Spectroscopy

Autor: Alejandro L. Briseno, George V. Nazin, Christian F. Gervasi, Stefan C. B. Mannsfeld, Dmitry A. Kislitsyn, Lei Zhang, Benjamen N. Taber

Publikováno v: The Journal of Physical Chemistry C. 119:26959-26967

Charge transport in electronic applications involving molecular semiconductor materials strongly depends on the electronic properties of molecular-scale layers interfacing with external electrodes. In particular, local variations in molecular environ

Self-Trapping of Charge Carriers in Semiconducting Carbon Nanotubes: Structural Analysis

Autor: Sergei Tretiak, Lyudmyla Adamska, George V. Nazin, Stephen K. Doorn

Publikováno v: The Journal of Physical Chemistry Letters. 6:3873-3879

The spatial extent of charged electronic states in semiconducting carbon nanotubes with indices (6,5) and (7,6) was evaluated using density functional theory. It was observed that electrons and holes self-trap along the nanotube axis on length scales
