In the energy range Ev to Ec there are no states.

Pirates are often engaged in _______ innocent sailors.

There are fears that the situation might ________ into full-scale war.

Section B Multiple Choice There are 10 incomplete sentences in this section. For each sentence there are four choices marked A), B), C) and D). Choose the ONE answer that best completes the sentence. A house with a dangerous gas _______ can be broken into immediately.

The electric field across the pn junction is found by integrating the density of electrons.

Potential energy is charge* potential = q V

Wo = Wn+ Wp is the total width of the depletion region under a zero applied voltage

Many holes can diffuse across the depletion region and enter the n-side. This results in the “injection of excess minority carriers”, i.e., holes into the n-region.

The negative polarity of the supply will reduce the potential barrier Vo by V because the applied voltage drops mostly across the depletion width W.

Boltzmann Statistics can only be used with nondegenerate semiconductors.

The bulk regions outside the SCL have high conductivities, due to the plenty of majority carriers in the bulk, in comparison with depletion region in which there are mainly immobile ions (with larger resistivity).
