Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
In this chapter, different structural, electronic and magnetic properties of
strained graphene nanoribbons are examined. All the calculations are performed by
using density functional theory. Compressive stress along a nanoribbon's longer axis
and tensile stress at the midpoint and perpendicular to the nanoribbon's plane are
studied. There are remarkable changes in the structures, including the formation of
nanoripples in the ribbons. The shape and size of the ribbons lead to variation in their
electronic and magnetic properties. Strained nanoribbons show tunable magnetic
properties that can be used for developing magnetic nano-switches.
