How to calculate dopant density from resistivity
I can get the sheet resistivity by using a 4-probe station,in order to get the dopant density of a S-doped InP,what else do I need to know?
答案
conductivity σ=1/ρ=e(μn*Nd+μp*Na)
and if it is a Si doped with P it is n-type
so σ=eμn*Nd
So you need to know the mobility relationship with Nd

已知函数f(x)=x,g(x)=alnx,a∈R.若曲线y=f(x)与曲线y=g(x)相交,且在交点处有相同的切线,求a的值和该切线方程.
