castep 幾何優(yōu)化后的晶格常數(shù)在哪里(正交晶系)?
|
|
請問SrAl2 空間群74 imma 正交晶系,進行幾何優(yōu)化后的晶格常數(shù)在哪里? 正交晶系 三個晶格常數(shù)不一樣,角度都是90度, 優(yōu)化前的晶格常數(shù):a=7.916, b=4.813, c=7.929. 是下面輸出中Real Lattice 再乘以2 嗎? 我在做優(yōu)化時選擇是允許轉(zhuǎn)化成原胞。 謝謝! 以下是castep 3D Atomistic.castep 文件輸出的一部分: BFGS: Geometry optimization completed successfully. ================================================================================ BFGS: Final Configuration: ================================================================================ ------------------------------- Unit Cell ------------------------------- Real Lattice(A) Reciprocal Lattice(1/A) -3.9592624 2.4082489 3.9689169 0.0000000 1.3045133 0.7915491 3.9592624 -2.4082489 3.9689169 0.7934793 0.0000000 0.7915491 3.9592624 2.4082489 -3.9689169 0.7934793 1.3045133 0.0000000 Lattice parameters(A) Cell Angles a = 6.101453 alpha = 99.081826 b = 6.101453 beta = 133.505356 c = 6.101453 gamma = 98.843307 Current cell volume = 151.372733 A**3 ------------------------------- Cell Contents ------------------------------- xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx x Element Atom Fractional coordinates of atoms x x Number u v w x x----------------------------------------------------------x x Al 1 0.338916 0.271123 0.432207 x x Al 2 0.338916 -0.093292 0.067793 x x Al 3 0.661084 -0.271123 0.567793 x x Al 4 -0.338916 0.093292 -0.067793 x x Sr 1 0.949496 0.699496 0.250000 x x Sr 2 0.050504 -0.699496 0.750000 x xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx |
