本文测量了硼离子注入多晶硅薄膜经热退火及激光退火后的电学性质
并用晶界陷阱模型进行了理论计算。计算结果与实验符合。发现经激光退火后

The electrical properties of boron-implanted polysilicon after thermal and laser annealing are measured
and theoretical calculations are made by using the grain boundary trapping model
giving results in good agreement with experiments.It is found that after laser annealing
when the grain size becomes large enough
the minimum of the mobility is not at N=N

but appears near N=10
