Abstract: On the basis of the relative experiment, the possible geometrical structures and relative stability of silicon-phosphorous clusters SinPm+(n+m =5) are explored by means of density functional theory (DFT) quantum chemical calculations(B3LYP/631G*). The effects of polarization functions and electron correlation are included in these calculations. As a result, the stability regularity of the SinPm+ cluster is obtained, that is, when n>m , the most stable structure of the clusters is similar to Sin+, otherwise, it is similar to Pm+.
