p-type substrate of having Miller index of (100) and (111)

[kimmylsm]

what is the obvios differences between p-type substrate of having Miller index of (100) and (111), beside (111) plane have higher atom density?

Welcome to the PF. What is the context of your question? Is this for a class or for a school project?

It is deposition thin film on the p-substrate.Does plane (111) or (100) of p-type subsrate affect the structural properties of thin film deposited?
