HCP材料
對金屬而言,每個原子具相同數目之最鄰近或相接觸的原子,此即配位數(coordination number)。 原子堆積因子(atomic packing factor;APF)是基於原子硬球模型假設,所有的原子球體在單位晶胞中占有體積之比率;亦即 體心立方晶體結構 The Body-Centered Cubic Crystal Structure 另一常見的金屬晶體結構也是具有立方體單位晶胞,...
Mechanical and electronic properties of palladium dihydrides (PdH2) as a function of pressure were studied by ab initio calculations based on density functional theory (DFT). The ab initio random structure searching technique was employed for screening potential PdH2crystal structures under high pressur...
1/2 atom per unit cell = 3 atoms therefore, the total number of atoms in a unit cell = 4 atoms . volume of hcp unit cell a unit cell is the smallest representation of an entire crystal. the hexagonal closest packed (hcp) has a coordination number of 12 and contains 6 atoms per ...
