声子谱计算中Q点的设置
|
|
在计算声子谱过程中,利用GS直接生成的正空间q点,与声子能带中的倒空间中高对称性点的设置有关么?GS生成的q点有很多,全都要放上去么? 以下是AlAs声子谱计算中的q点: 一、 GS生成的q点: nqpt 1 qpt2 0.00000000E+00 0.00000000E+00 0.00000000E+00 qpt3 0.00000000E+00 0.00000000E+00 0.00000000E+00 qpt4 2.50000000E-01 0.00000000E+00 0.00000000E+00 qpt5 5.00000000E-01 0.00000000E+00 0.00000000E+00 qpt6 2.50000000E-01 2.50000000E-01 0.00000000E+00 qpt7 5.00000000E-01 2.50000000E-01 0.00000000E+00 qpt8 -2.50000000E-01 2.50000000E-01 0.00000000E+00 qpt9 5.00000000E-01 5.00000000E-01 0.00000000E+00 qpt10 -2.50000000E-01 5.00000000E-01 2.50000000E-01 二、倒空间高对称性点 nph1l 71 ! number of phonons in list 1 qph1l 0.0000 0.0000 0.0000 1.0 !(gamma point) 0.0375 0.0375 0.0750 1.0 0.0750 0.0750 0.1500 1.0 0.1125 0.1125 0.2250 1.0 0.1500 0.1500 0.3000 1.0 0.1875 0.1875 0.3750 1.0 0.2250 0.2250 0.4500 1.0 0.2625 0.2625 0.5250 1.0 0.3000 0.3000 0.6000 1.0 0.3375 0.3375 0.6750 1.0 0.3750 0.3750 0.7500 1.0 !(K point) 0.3875 0.3875 0.7750 1.0 0.4000 0.4000 0.8000 1.0 0.4125 0.4125 0.8250 1.0 0.4250 0.4250 0.8500 1.0 0.4375 0.4375 0.8750 1.0 0.4500 0.4500 0.9000 1.0 0.4625 0.4625 0.9250 1.0 0.4750 0.4750 0.9500 1.0 0.4875 0.4875 0.9750 1.0 0.5000 0.5000 1.0000 1.0 !(X point) 0.5500 0.5500 1.0000 1.0 0.6000 0.6000 1.0000 1.0 0.6500 0.6500 1.0000 1.0 0.7000 0.7000 1.0000 1.0 0.7500 0.7500 1.0000 1.0 0.8000 0.8000 1.0000 1.0 0.8500 0.8500 1.0000 1.0 0.9000 0.9000 1.0000 1.0 0.9500 0.9500 1.0000 1.0 1.0000 1.0000 1.0000 1.0 !(gamma point) 0.9500 0.9500 0.9500 1.0 0.9000 0.9000 0.9000 1.0 0.8500 0.8500 0.8500 1.0 0.8000 0.8000 0.8000 1.0 0.7500 0.7500 0.7500 1.0 0.7000 0.7000 0.7000 1.0 0.6500 0.6500 0.6500 1.0 0.6000 0.6000 0.6000 1.0 0.5500 0.5500 0.5500 1.0 0.5000 0.5000 0.5000 1.0 !(L point) 0.5000 0.4500 0.5000 1.0 0.5000 0.4000 0.5000 1.0 0.5000 0.3500 0.5000 1.0 0.5000 0.3000 0.5000 1.0 0.5000 0.2500 0.5000 1.0 0.5000 0.2000 0.5000 1.0 0.5000 0.1500 0.5000 1.0 0.5000 0.1000 0.5000 1.0 0.5000 0.0500 0.5000 1.0 0.5000 0.0000 0.5000 1.0 !(X point) 0.5000 0.0250 0.5250 1.0 0.5000 0.0500 0.5500 1.0 0.5000 0.0750 0.5750 1.0 0.5000 0.1000 0.6000 1.0 0.5000 0.1250 0.6250 1.0 0.5000 0.1500 0.6500 1.0 0.5000 0.1750 0.6750 1.0 0.5000 0.2000 0.7000 1.0 0.5000 0.2250 0.7250 1.0 0.5000 0.2500 0.7500 1.0 !(W point) 0.5000 0.2750 0.7250 1.0 0.5000 0.3000 0.7000 1.0 0.5000 0.3250 0.6750 1.0 0.5000 0.3500 0.6500 1.0 0.5000 0.3750 0.6250 1.0 0.5000 0.4000 0.6000 1.0 0.5000 0.4250 0.5750 1.0 0.5000 0.4500 0.5500 1.0 0.5000 0.4750 0.5250 1.0 0.5000 0.5000 0.5000 1.0 !(L point) |
