Single-Atom Scale Structural Selectivity in Te Nanowires Encapsulated inside Ultra-Narrow, Single-Walled Carbon Nanotubes
Paulo V. C. Medeiros, Samuel Marks, Jamie M. Wynn +5
Extreme nanowires (ENs) represent the ultimate class of crystals: They are the smallest possible periodic materials. With atom-wide motifs repeated in one dimension (1D), they offe…
Encapsulated Nanowires: Boosting Electronic Transport in Carbon Nanotubes
Andrij Vasylenko, Jamie Wynn, Paulo Medeiros +3
The electrical conductivity of metallic carbon nanotubes (CNTs) quickly saturates with respect to bias voltage due to scattering from a large population of optical phonons. Decay o…
Unfolding spinor wavefunctions and expectation values of general operators: Introducing the unfolding-density operator
Paulo V. C. Medeiros, Stepan S. Tsirkin, Sven Stafström +1
We show that the spectral weights used for the unfolding of two-component spinor eigenstates $| {ψ_{m\vec K}^\mathrm{SC}} > = | α> | {ψ_{m\vec{K}}^\mathrm{SC,…
Optical and magnetic excitations of metal-encapsulating Si cages: A systematic study by time-dependent density functional theory
Micael J. T. Oliveira, Paulo V. C. Medeiros, José R. F. Sousa +2
Systematic study of the optical and magnetic excitations of twelve MSi and four MSi transition metal encapsulating Si cages has been carried out by employing real tim…
