Ferromagnetism and optical properties of SnS₂ doped with two impurities: first-principles calculations

Abstract

Based on the first principles of the GGA method, the magnetic and optical properties of intrinsic SnS2, Fe, Cr mono-doped SnS2 and (Fe, Cr) co-doped SnS2 are studied. The results...

Recent advances of substitutionally doped tin dichalcogenides

“…117 Fe-and Mn-doped SnS 2 /SnSe 2 are magnetic semiconductors and have potential for spintronic applications, which have been verified experimentally. 30,31,40,103,118,119 Because of the potential spintronic applications for high capacity storage and fast computing, further experimental investigations of other transition metal doping in tin dichalcogenides, such as Cr, Co, and Ni, are desired. Further potential applications of doped tin dichalcogenides, such as photocatalysis, batteries, and gas sensing, also deserve experimental verification.…”

“…58 In addition, due to the enhanced phonon scattering between van der Waals layers of Cl-doped SnSe 2 , the thermal conductivity was effectively reduced. 59,103 Therefore, the thermoelectric figure of merit ( zT ) is significantly improved and has attracted attention in the field of thermoelectricity. With the increase of Cl concentration, the zT value at 610 K increases from 0.15 to 0.226.…”

Tuning the magnetic ordering driven by cationic antisite defects in the Li(ZnMn)As system

“…Dilute magnetic semiconductors (DMSs) had the unique advantage of manipulating the spin and charge of electrons simultaneously and held extensive promise for novel spintronic devices and quantum computing. 1–6 Yu et al 7 found that V-, Mn-, Fe-, and Co-doped MoSe 2 /h-BN systems exhibited a half-metallic state and magnetic behavior, while there was no spin polarization in the Ni-doped case. Li et al 8 processed ZnO-based thin DMSs with high magnetic field treatments and improved the ferromagnetism at room temperature by adjusting the microstructure and magnetic properties.…”

Structure, Electron Density Distribution using Maximum Entropy Method, Optical and Magnetic Characteristics of Fe Doped SnS2

“…[9] It has been researched for a variety of applications, including spintronics, optoelectronics, and photocatalysis. [9,16,17] Due to the spin polarization of the Fe atoms and their hybridization with the S atoms, [9] doping SnS 2 with Fe can induce ferromagnetism in the monolayer. The ferromagnetic order is perpendicularly anisotropic and has a Curie temperature of ≈31 K. [9] Fe enrichment also modifies the optical properties of SnS 2 by introducing novel visible and infrared absorption peaks.…”
