怎么計算和分析電荷轉(zhuǎn)移量
|
|||
|
親愛的蟲友們, 我想計算石墨烯和一些官能團之間的電荷轉(zhuǎn)移量,請問應(yīng)該怎算。 我先計算了charge density difference,但是這個結(jié)果并不能看出電荷轉(zhuǎn)移的多少,只能定性的看出電荷轉(zhuǎn)移的方向。 然后利用projwfc計算了lowdin charge,比如我算的結(jié)果如下: 。。。。 Lowdin Charges: Atom # 1: total charge = 3.9529, s = 0.8977, p = 3.0553, Atom # 2: total charge = 3.9529, s = 0.8977, p = 3.0552, Atom # 3: total charge = 3.9531, s = 0.8941, p = 3.0589, Atom # 4: total charge = 3.9617, s = 0.8999, p = 3.0617, Atom # 5: total charge = 3.9498, s = 0.8977, p = 3.0521, Atom # 6: total charge = 3.9570, s = 0.8977, p = 3.0593, Atom # 7: total charge = 3.9617, s = 0.8999, p = 3.0618, Atom # 8: total charge = 3.9530, s = 0.8941, p = 3.0589, Atom # 9: total charge = 3.7646, s = 0.8906, p = 2.8741, Atom # 10: total charge = 3.7646, s = 0.8906, p = 2.8740, Atom # 11: total charge = 3.9531, s = 0.8941, p = 3.0589, Atom # 12: total charge = 3.9617, s = 0.8999, p = 3.0617, Atom # 13: total charge = 3.9569, s = 0.8978, p = 3.0592, Atom # 14: total charge = 3.9498, s = 0.8977, p = 3.0521, Atom # 15: total charge = 3.9617, s = 0.8999, p = 3.0618, Atom # 16: total charge = 3.9530, s = 0.8941, p = 3.0589, Atom # 17: total charge = 3.9529, s = 0.8977, p = 3.0553, Atom # 18: total charge = 3.9529, s = 0.8977, p = 3.0552, Atom # 19: total charge = 6.3370, s = 1.7571, p = 4.5798, 第19個原子為氧原子,其他的都為碳原子。請問我在這個例子中得到的電荷轉(zhuǎn)移量該怎么計算? |

碳原子最外層有4個電子,氧有6個電子,把你算出來的電荷分別減去相應(yīng)的電子數(shù)目就可以了。 比如氧的電荷為6.3370-6=0.337,也就是得到0.337電子,凈電荷為-0.337 |
