2022年2月1日 · Here, we carry out a comparative investigation on both bulk and monolayer of SiSe 2 to understand their thermoelectric properties with the aid of the Boltzmann transport theory and the first-principles density functional theory (DFT). The results show that the SiSe 2 …

2024年1月10日 · Herein, we introduce the synthesis of layered SiSe 2 through a facile solid-state synthetic route and demonstrate its versatility as a sulfide solid electrolyte (SE) additive for all-solid-state batteries (ASSBs) and as an anode material for Li-ion batteries (LIBs).

2021年4月1日 · SiSe 2 homo-bilayer having moderate band gap is studied and thermodynamically tested. Higher electron mobilities (10 4 cm 2 V −1 s −1) are predicted along both x- and y-directions. Absorption spectrum covers near infrared, visible, and UV region indicating its usefulness in optoelectronics devices.

SiSe2 is Silicon Disuphide structured and crystallizes in the orthorhombic Ibam space group. The structure is one-dimensional and consists of two SiSe2 ribbons oriented in the (1, 0, 0) direction. Si4+ is bonded to four equivalent Se2- atoms to form edge-sharing SiSe4 tetrahedra. All Si–Se bond lengths are 2.30 Å.

基于第一性原理计算，我们从理论上探讨了Si 2 Se 2和SiSe 2纳米片作为潜在阴极电催化剂的应用潜力。 提出了不同的电化学还原路径来理解放电过程。 例如，对于Li-O 2电池，电催化剂表面的主要产物是LiO 2和Li 2 O 2 ， 而SiSe 2的充放电过电位小于0.46 V。

与特征明确的高温形式的SiSe 2（边缘共享的SiSe 4四面体形成一维链）相反，在低温多晶型物的晶体结构中，通过边缘和拐角形成了二维褶皱层共享SiSe 4四面体。

SiSe2 is Cyanogen Chloride-derived structured and crystallizes in the orthorhombic Ibam space group. The structure is zero-dimensional and consists of four $l^ {1}-selanyl (selanylidene)silicon molecules. Si4+ is bonded in a linear geometry to two equivalent Se2- atoms. Both Si–Se bond lengths are 2.09 Å.

2022年10月18日 · In this work, based on first-principles calculations, we theoretically predict two kinds of two-dimensional tetragonal Si–Se compounds, Si 2 Se 2 and SiSe 2, as the anode materials for alkali metal-ion batteries. The results show that Si 2 Se 2 and SiSe 2 are thermally and dynamically stable and have good electronic conductivity.
