文摘The geometrical structures and binding energies of Ge_mSi_n mixed clusters(s=m+n≤10) have been optimized based upon the nonorthogonal tight-binding scheme. Ge_mSi_n mixed clusters are found similar in structures with Si_n and Ge_n(but with lower symmetries) and the binding energies of the mixed clusters are between the corresponding values of the Si_n and Ge_n.
