Pure spin current injection of single-layer monochalcogenides
Bernardo S. Mendoza, Lucila Juarez-Reyes, Benjamin M. Fregoso
We compute the spectrum of pure spin current injection in ferroelectric single-layer SnS, SnSe, GeS, and GeSe. The formalism takes into account the coherent spin dynamics of optica…
Second-Harmonic Generation in Nano-Structured Metamaterials
Ulises R. Meza, Bernardo S. Mendoza, W. Luis Mochán
We conduct a theoretical and numerical study on the second-harmonic (SH) optical response of a nano-structured metamaterial composed of a periodic array of inclusions. Both the inc…
Pure Spin Current Injection in Hydrogenated Graphene Structures
Reinaldo Zapata-Peña, Bernardo S. Mendoza, Anatoli I. Shkrebtii
We present a theoretical study of spin-velocity injection (SVI) of a pure spin current (PSC) induced by a linearly polarized light that impinges normally on the surface of two 50\%…
Large bulk photovoltaic effect and spontaneous polarization of single-layer monochalcogenides
Tonatiuh Rangel, Benjamin M. Fregoso, Bernardo S. Mendoza +3
We use a first-principles density functional theory approach to calculate the shift current and linear absorption of uniformly illuminated single-layer Ge and Sn monochalcogenides.…
