Angela sees a puzzle that uses a board with 20 holes drilled into it. There are 18 pegs in the holes, and the goal of the puzzle is to move the pegs by hopping them into the open holes until both holes are at one end of the board. How could Angela use the puzzle to model semiconductors?
Answer
A
as an n-type semiconductor with the pegs representing electrons and the holes representing positive charges
B
as a p-type semiconductor with the holes representing electrons and the pegs representing positive charges
C
as a p-type semiconductor with the pegs representing electrons and the holes representing positive charges
D
as an n-type semiconductor with the holes representing electrons and the pegs representing positive charges
