Anti-perovskites A3SnO(A=Ca,Sr,and Ba)are an important class of materials due to the emergence of Dirac cones and tiny mass gaps in their band structures originating from an intricate interplay of crystal symmetry,spin–orbit coupling,and band *** provides an exciting playground for modulating their electronic properties in the two-dimensional(2D)***,we employ first-principles density functional theory(DFT)calculations by combining dispersion-corrected SCAN+rVV10 and mBJ functionals for a comprehensive side-by-side comparison of the structural,thermodynamic,dynamical,mechanical,electronic,and thermoelectric properties of bulk and monolayer(one unit cell thick)A3SnO *** results show that 2D monolayers derived from bulk A3SnO anti-perovskites are structurally and energetically ***,Rashba-type splitting in the electronic structure of Ca3SnO and Sr3SnO monolayers is observed owing to strong spin–orbit coupling and inversion *** the other hand,monolayer Ba3SnO exhibits Dirac cone at the high-symmetryΓpoint due to the domination of band *** on the predicted electronic transport properties,it is shown that inversion asymmetry plays an essential character such that the monolayers Ca3SnO and Sr3SnO outperform thermoelectric performance of their bulk counterparts.

为了探索腐植酸(HA)的施用方法,在白沙瓦开伯尔-普什图省农业大学的农业研究农场内进行了完全随机区组设计试验,并设置3次重复。HA的施用方法分为浸种、叶片喷施和土壤施用3种。HA的施用方法对绿豆单株结荚数、每荚粒数、千粒重和籽粒产量具有显著影响,而对绿豆生物量影响不大。每公顷土地施用3 kg HA能显著提高绿豆结荚率、千粒重和产量;而土壤中加入1 kg/hm^2和2 kg/hm^2 HA,浓度为0、1%、2%的HA浸种和0.01%、0.05%、0.1%的HA叶面喷施3种方法所得到的结果在统计学上相似。由此得出结论:3种施用HA的方法均能显著提高绿豆产量及其构成因子。
