What is the main difference between ny7olu2p) (cq j+f 2jmf sunw*:-type anv* x9 i4:a3n 1t 2wgjc;8znfmvjco)p jd p-type semiconductors?
参考答案: The main difference between n-type and p-type semiconductors is the type of atom used for the doping impurity. When a semiconductor such as Si or Ge, each atom of which has four electrons to share, is doped with an element that has five electrons to share (such as As or P), then it is an n-type semiconductor since an extra electron has been inserted into the lattice. When a semiconductor is doped with an element that has three electrons to share (such as Ga or In), then it is a p-type semiconductor since an extra hole (the lack of an electron) has been inserted into the lattice.
