Silicon, with 4 valence electrons, is the most widely used material for photovoltaic devices even though it is only a semi- conductor. The conductivity can be improved with dopants. Which of these elements would best serve to create a p-type semiconductor when added to silicon? A. germanium (Ge) B. selenium (Se) C. gallium (Ga) D. arsenic (As)
The "doping" of a semiconductor to improve its performance means. A. mixing large amount of a metal with small amounts of a semiconductor so that the metal itself becomes a semiconductor. B. slightly raising the temperature of a pure semiconductor to improve the ability of its electrons to flow from atom to atom. C. adding small amounts of other elements to the pure semiconductor to change the freedom of electron motion throughout the crystal. D. fusing layers of two different pure semiconductors together to give the electrons that absorb the sunlight characteristics of the electrons of both semiconductors. Rorot Selection
