The filtered states of GeSe by a Ru dimer could lead to superior NRR catalytic activity for the promoted activation inert nitrogen bonds and subsequent reduction hydrogenation.

Germanium monoselenide (GeSe) is an emerging promising photovoltaic absorber material due to its attractive optoelectronic properties as well non-toxic and earth-abundant constitutes. However, all previously reported GeSe solar cells rely on a superstrate configuration coupled with CdS buffer layer, suffer from unsatisfactory performance. Here we demonstrate that this low efficiency arises the ...

The stiff competition in the market, and continuous pressures from various stakeholders such as customers, business owners, environmental authorities, society, general, to produce unique products services, protect environment, obtain competitive advantage continue challenge sustainability of enterprises especially small ones. Accordingly, minimize effect these challenges pressures, can improve ...

Group-IV monochalcogenides have attracted much attention due to their potential of ferroelectric and multiferroic properties. Recently, centrosymmetric gamma-phase GeSe in a double-layer honeycomb lattice has been theoretically predicted, but the synthesized showed noncentrosymmetric atomic structure, leading possibility ferroelectricity spin-splitting. Here, we study quasiparticle band structu...

The two-dimensional heterostructure is a promising research direction in photodetection. However, developing good photodetector with high responsivity and fast speed still challenging. Herein, we fabricate high-performance self-powered broadband (355–1064 nm) based on near-broken-gap GeSe/SnS 2 /InSe heterostructure, where SnS used as potential hole barrier layer. device shows an ultrahigh open...

Recently synthesized novel phase of germanium selenide (γ-GeSe) adopts a hexagonal lattice and surprisingly high conductivity than graphite. This triggers great interests in exploring its potential for thermoelectric applications. Herein, we explored the performance monolayer γ-GeSe other isostructural γ-phase group-IV monochalcogenides γ-GeX (X = S, Se Te) using density functional theory Boltz...

An ideal atomistic model of a disordered material should contradict no experiments, and should also be consistent with accurate force fields seither ab initio or empiricald. We make significant progress toward jointly satisfying both of these criteria using a hybrid reverse Monte Carlo approach in conjunction with approximate first-principles molecular dynamics. We illustrate the method by stud...

Solvothermal reactions of elements Ge and Se with Ln(2)O(3) in a pentadentate polyamine, tetraethylenepentamine (tepa), produced novel neutral lanthanide-selenidogermanate polymers [{Ln(tepa)(μ-OH)}(2)(μ-Ge(2)Se(8))](n) (Ln = Eu 1, Gd 2, Dy 3). The reaction with Dy(2)O(3) in ethylenediamine (en) afforded an ionic selenidogermanate [{Dy(en)(3)}(2)(μ-OH)(2)]Ge(2)Se(6) (4). In compounds 1-3, the L...
