Two-dimensional (2D) semiconducting tin disulfide (SnS2) has been widely used for optoelectronic applications.To functionalize SnS2 for extending its application,we investigate the stability,electronic and magnetic properties of substitutional doping by high throughput first-principles calculations.There are a lot of elements that can be doped in monolayer SnS2.Nonmetal in group A can introduce p-type and n-type carriers,while most metals in group A can only lead to p-type doping.Not only 3d,but also 4d and 5d transition metals in groups VB to ⅧB9 can introduce magnetism in SnS2,which is potentially applicable for spintronics.This study provides a comprehensive view of functionalization of SnS2 by substitutional doping,which will guide further experimental realization.

Photonic-plasmonic hybrid microcavities,which possess a higher figure of merit Q/V (the ratio of quality factor to mode volume) than that of pure photonic microcavities or pure plasmonic nano-antennas,play key roles in enhancing light-matter interaction.I
A surrounding electromagnetic environment can engineer spontaneous emissions from quantum emitters through the Purcell effect.For instance,a plasmonic antenna can efficiently confine an electromagnetic field and enhance the fluorescent process.In this stu
Recent years,huge progress of first-principles methods has been witnessed in calculating the quasiparticle band gaps,with many-body perturbation theory in the GW approximation being the standard choice,where G refers to Green\'s function and W denotes t
Motivated by the fact that Weyl fermions can emerge in a three-dimensional topological insulator on breaking either time-reversal or inversion symmetries,we propose that a topological quantum phase transition to a Weyl semimetal phase occurs under the off
In blue quantum dot light emitting diodes (QLEDs),electron injection is insufficient,which would degrade device efficiency and stability.Herein,we employ chlorine passivated ZnO nanoparticles as electron transport layer to facilitate electron injection in
We study the possibility to realize a Majorana zero mode that is robust and may be easily manipulated for braiding in quantum computing in the ground state of the Kitaev model in this work.To achieve this we first apply a uniform[111]magnetic field to the

Brownian motors and self-phoretic microswimmers are two typical micromotors,for which thermal fluctuations play different roles.Brownian motors utilize thermal noise to acquire unidirectional motion,while thermal fluctuations ran-domize the self-propulsio
