Raman spectra and infrared intensities of graphene-like clusters in compared to epitaxial graphene on Si
Seyed Sajad Sadeghi, Hamidreza Simchi
There are several growing methods for graphene. In this study, the growth of graphene-like clusters on the SiC wafers is done by annealing the wafers in a vacuum evaporation system…
Spin polarization in Lateral two-dimensional Heterostructures
S. Hannan Mouasvi, H. Simchi
In this work, we study the spin polarization in the Transition metal dichalcogenide heterostructures by using the non-equilibrium Green's function (NEGF) m…
Interface Dark Excitons at Sharp Lateral Two-Dimensional Heterostructures
Hamidreza Simchi
We study the dark excitons at the interface of sharp lateral heterostructure of two-dimensional transition metal dichalcogenides. By introducing a low-energy effective Hamiltonian…
A simple Tight-Binding Approach to Topological Superconductivity in Monolayer MoS2
Hamidreza Simchi
Monolayer molybdenum disulfide (MoS2) has a honeycomb crystal structure. We consider the triangular sublattice of molybdenum atoms and introduce a simple tight-binding Hamiltonian…
Phase Transition and Field Effect Topological Quantum Transistor made of monolayer MoS2
H. Simchi, M. Simchi, M. Fardmanesh +1
We study topological phase transitions and topological quantum field effect transistor in monolayer Molybdenum Disulfide (MoS2) using a two-band Hamiltonian model. Without consider…
Tunable free energy and heat flux between two-dimensional materials
Hamidreza Simchi
We study the free energy across a stratified media made by graphene (G) and/or molybdenum disulfide (MoS2). The flux depends not only on the number of G/MoS2 layers but also on the…
