Some Properties of Bilayer Graphene Nanoribbons
Maher Ahmed
In this work the tight binding model calculations are carried out for AA-Bilayer Graphene nanoribbons as an example of bilayer systems. The effects of edges, NNN hopping, and impur…
The next nearest neighbor effect on the 2D materials properties
Maher Ahmed
In this work, the effect of introducing next nearest neighbor (NNN) hopping to the 2D materials was studied using the graphene 2D honeycomb two sublattice as an example. It is foun…
Understanding of hopping matrix for 2D materials taking 2D honeycomb and square lattices as study cases
Maher Ahmed
In this work, a trial understanding for the physics underling the construction of exchange (hopping) matrix in Heisenberg model (tight binding model) for 2D materials…
SpinWaves in Ferromagnetic Dots 2D Honeycomb Lattice Stripes
Maher Ahmed
In this work, the spin wave calculations were carried out using the Heisenberg Hamiltonian to study the allowed spin waves of zigzag and armchair edged stripes for ferromagnetic na…
The effect of edge and impurities sites properties on their localized states in semi-infinite zigzag edged 2D honeycomb graphene sheet
Maher Ahmed
In this work, the tridiagonal method is used to distinguish between edges modes and area modes to study the edge sites properties effect on edge localized states of semi-infinite z…
Spin Waves in 2D ferromagnetic square lattice stripe
Maher Z. Ahmed
In this work, the area and edges spin wave calculations were carried out using the Heisenberg Hamiltonian and the tridiagonal method for the 2D ferromagnetic square lattice stripe,…
