(a) You need to dope Si to produce free positive charge carriers. (1) Explain how this process will be achieved by sketching a 2D representation of the Si crystal lattice to show the effect of this doping process. Clearly explain what impurities you will use for this process. (ii) Sketch the energy band diagram of this doped material in (i) at 0 K and identify all the important features in your diagram. (iii) Now sketch the same energy band diagram...

Could you please explain why the answer is C. I dont understand
how determing the direction of the force allows us to understand
charge distribution.

Suppose we had a large, positively charged plate in an upright (vertical) position and a point charge with positive charge +Q. In lecture, you saw that a large charged plate gives rise to an electric field which is constant in space: we will call this electric field Eplate. Let us suppose also that we had a s bl with positive charge +q and...
