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.
Keywords: Density functional theory, Graphene nanoribbons, Magnetism, Nanoripples, Strain.
