2D Materials for Quantum Technologies

2-dimensional and layered materials, such as transition metal dichalcogenides (TMD) provide a promising platform for developing components for novel semiconductor- superconductor hybrid devices, such as sensors, switches, qubits and logical components in nanometer-scale electronics. Especially edges and interfaces lead to tunable electronic properties, which can be utilized in, e.g, control of spin polarized currents or proximity induced superconductivity in semimetallic or semiconducting heterostructures. In modeling appropriate materials, we utilize Nambu-Gorkov Green’s function approach in materials specific tight-binding basis, which allow controlled inclusion of, e.g., Hamiltonian matrix elements for spin-orbit coupling or superconducting pairing, as well as coupling to bosonic modes in form of self-energies in Dyson’s equation.

Among our recent studies, we have modeled proximity induced superconductivity in monolayer MoS2 on Pb [ACS Nano 2020 ], which project was lead by prof. Maria Iavarone at Temple University. Among the earlier highlights are as study of edge states of Ag/Si(111) reconstructed surfaces [Applied Physics Letters 2019 ], modeling superconductivity in metal decorated graphene [Journal of Physics 2017 ], electrically tunable spin-polarized tunneling channels in silicene sheets [APL 2014 ] and modeling interplay between strain and doping in high-temperature superconductors [Nano Letters2014 ].
