First principles study of the structure, electronic state and stability of AlnAsm− anions
چکیده انگلیسی
Structural and electronic properties of semiconductor binary microclusters AlnAsm− anions have been investigated using the B3LYP-DFT method in the ranges of n = 1,2 and m = 1-7. Full structural optimization, adiabatic electron affinities calculation and frequency analysis are performed with the basis of 6-311 + G(d). The charged-induced structural changes in these anions have been discussed. The strong As-As bond is also favored over Al-As bonds in the AlnAsm− anions in comparison with corresponding neutral cluster. Among different AlAsm− and Al2Asm− (m = 1-7) anions, AlAs4− and Al2As3− are most stable.
