Question

1.We have a semiconductor, AlP, which is a p-type semiconductor. We want to incorporate some doping to tune its

carrier concentration. Based on what you learned, please select proper dopants for p-type doing (increase hole concentration) and n-type doping (dope electron into the system to reduce hole concentration). Please also explain why you would select that one.


2. Please compare Graphene and Phosphorene based on what you learned (Hints: they are all two-dimensional materials, but one is flat, and another is distorted, why? Also, bond length etc).
