Electrical properties of heavily doped polycrystalline

The electrical properties of polycrystalline silicon-germanium (poly-Si/sub 1/spl minus/x/Ge/sub x/) films with germanium mole fractions up to 0.56 doped by high-dose ion implantation are presented. The resistivity of heavily doped p-type (P/sup +/) poly-Si/sub 1/spl minus/x/Ge/sub x/ is much lower than that of comparably doped poly-Si, because higher levels of boron activation and higher hole
