- In a P-type semiconductor a. both holes and free electrons are equal in number b. holes are minority charge carriers C. holes are majority charge carriers d. free electrons are majority charge carriersn-type semiconductors a. are produced when Indium is added as an impurity to Germanium b. uses trivalent impurity c. are produced when phosphorous is added as an impurity to silicon d. are produced when boron is added as an impurity to silicona. If you do not go completely around the loop when applying Kirchhoff’s voltage law, then the algebraic sum of the voltages cannot be determined the algebraic sum of the voltages will always be positive the algebraic sum of the voltages will always be negative the algebraic sum is the voltage between the start and finish points b. A p -type semiconductor is a semiconductor doped with impurity atoms whose electron valence is +4 pentavalent impurity atoms trivalent impurity atoms
- What type of atom is needed as a dopant in a p-type semiconductor? atoms that have fewer electrons and protons than the semiconductor atoms being replaced atoms that have more electrons and protons than the semiconductor atoms being replaced O atoms that have fewer valence electrons than the semiconductor atoms being replaced atoms that have more valence electrons than the semiconductor atoms being replaced Why is it called p-type? The term p-type semiconductor means that this semiconductor is paramagnetic. O The term p-type semiconductor refers to the positively charged particles which are added to the semiconductor; in the result it is fully positively charged. O The term p-type semiconductor means that we use phosphorus as a dopant. O The term p-type semiconductor refers to the electron "holes" which can be viewed as positive areas in the sea of electrons.Which of the following circuit elements is a typical example of semiconductor material?
