Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

At present, various theoretical research methods are intensively used to interpret experimental results related to the study of the properties of defects in solids. Progress in this direction is possible thanks to the improvement of computer technology and the development of modern quantum chemical packages. The paper presents the results of computer simulation of the density of states and the total energy of an ideal NaF nanocrystal (Na13F14, Na4F5, Na22F23) and with the simplest point defects in various cluster compounds (Na12F13, Na21F22). Simulation of characteristics is implemented in the Atomistix ToolKit with Virtual NanoLab program in GGA (generalized gradient approximation) functionality. Objects studied are quantum dots. The results obtained may be useful in the study of nanocrystals.
