Resistivity in metals can be rationalized as follows (select all relevant answers; wrong answers, if selected will be penalized): Select one or more: a. It increases with temperature; b. Defects in the lattice affect resistivity; c. Defects in the lattice DO NOT affect resistivity; O d. Vibrations of the lattice causes stronger scattering of the electrons at higher temperatures; e. It decreases with temperature; Of. Electrons move faster at higher temperatures leading to decrease in overall resistivity;
Charge carries in p-doped semiconductors can be rationalized as follows (select all relevant answers; wrong answers, if selected will be penalized): Select one or more: a. Number of charge carriers increases with temperature; b. Number of charge carriers in p-doped semiconductors within technologically important temperature range is fully defined by impurities (atoms with fewer electrons) introduced in a controlled fashion; c. Both electrons and holes act as charge carries within technologically important temperature range; d. Number of charge carriers in p-doped semiconductors within technologically important temperature range is fully defined by impurities (atoms with greater number of electrons) introduced in a controlled fashion; e. Only electrons act as charge carriers within technologically important temperature range; Of. Only holes act as charge carriers within technologically important temperature range; Og. Number of charge carriers increases with temperature, and then has a plateau within technologically important temperature range before sharply increasing further at higher temperatures;
