New mechanism of plasmons specific for spin-polarized nanoparticles (open access)

New mechanism of plasmons specific for spin-polarized nanoparticles

This article experimentally shows that Co nanoparticles with a single-domain crystal structure support a plasmon resonance at approximately 280 nm with better quality than gold nanoparticle resonance in the visible. The magnetic nature of these nanoparticles suggests a new type of these plasmons.

Giant spin Hall effect in two-dimensional monochalcogenides (open access)

Giant spin Hall effect in two-dimensional monochalcogenides

This article, using calculations from first principles, reveals for the first time giant intrinsic spin Hall conductivities (SHC) in these materials. In particular, the article shows that the SHC resonances can be easily tuned by combination of strain and doping and, in some cases, strain can be used to induce semiconductor to metal transition that makes a giant spin Hall effect possible even in absence of doping.

Unexpected Structures for Intercalation of Sodium in Epitaxial Graphene-SiC Interfaces (open access)

Unexpected Structures for Intercalation of Sodium in Epitaxial Graphene-SiC Interfaces

In this paper, the authors show using scanning tunneling microscopy, spectroscopy, and ab initio calculations that several intercalation structures exist for Na in epitaxial graphene on SiC(0001). Intercalation takes place at room temperature and Na electron-dopes the graphene. It intercalates in-between single-layer graphene and the carbon-rich interfacial layer. It also penetrates beneath the interfacial layer and decouples it to form a second graphene layer. This decoupling is accelerated by annealing and is verified by direct Na deposition onto the interface layer. The authors' observations show that intercalation in graphene is fundamentally different than in graphite and is a versatile means of electronic control.

Development of a Thulium Fiber Laser for an Atomic Spectroscopy Experiment (open access)

Development of a Thulium Fiber Laser for an Atomic Spectroscopy Experiment

This article is a simplified analysis of a convenient thulium fiber laser source with 3 W of output power operating at a wavelength of 2059 nm with a slope efficiency of 49% with respect to input pump power and 60% with respect to absorbed pump power. The laser was applied in an atomic helium spectroscopy experiment to quench ³He (2058.63 nm) and ⁴He (2058.69 nm) meta-stable singlets (2¹S0), allowing for further investigation of the helium fine structure.
