Strong Fermi-Level Pinning in GeS-Metal Nanocontacts. [PDF]
J Phys Chem C Nanomater Interfaces, 2022 Germanium sulfide (GeS) is a layered monochalcogenide semiconductor with a band gap of about 1.6 eV. To verify the suitability of GeS for field-effect-based device applications, a detailed understanding of the electronic transport mechanisms of GeS-metal junctions is required.

Electronic stripe patterns near the fermi level of tetragonal Fe(Se,S) [PDF]
npj Quantum Materials, 2023 FeSe1−x S x remains one of the most enigmatic systems of Fe-based superconductors. While much is known about the orthorhombic parent compound, FeSe, the tetragonal samples, FeSe1−x S x with x > 0.17, remain relatively unexplored.

Asymptotic Pomeranchuk instability of Fermi liquids in half-filled Landau levels [PDF]
Scientific Reports, 2023 We present a theory of spontaneous Fermi surface deformations for half-filled Landau levels (filling factors of the form $$\nu =2 \, n+1/2$$ ν = 2 n + 1 / 2 ).

Estimating the quasi-Fermi level of holes at the surface of semiconductor photoanodes using outer-sphere redox couples [PDF]
Nature CommunicationsSemiconductor electrodes can catalyze photo-induced redox reactions with light illumination. Photoexcitation produces excited carriers that subsequently transfer to the front and back contacts as determined by the bulk and surface properties of the ...

A full gap above the Fermi level: the charge density wave of monolayer VS2 [PDF]
Nature Communications, 2021 A charge density wave (CDW) normally creates a gap at the Fermi level, inducing a metal-insulator transition. Here, the authors report that a CDW gap resides in the unoccupied states but induces a topological metal-metal transition at the Fermi level in ...
