Possible geometrical structures and relative stability of semiconductor microclusters ganpn ( n = 1 - 5 ) are studied by using density functional calculations with generalized gradient approximation ( b3lyp ). for the most stable isomers of ganpn ( n = 1 - 4 ) clusters, the electronic structures, vibrational properties, dipole moments, polarizability and ionization potential are analyzed using hf, mp2, cisd and b3lyp methods with different basis sets
用梯度修正的密度泛函方法（ b3lyp 6 - 31g ）優化了ga _ np _ n （ n = 1 - 5 ）團簇的可能幾何構型，計算了各穩定構型的的振動光譜，並用不同方法（ hf 、 mp2 、 cisd等）研究了各穩定構型的電子結構、電離勢、偶極矩和極化率等性質。
