Boron atoms are added to a si film resulting in an impurity density of 4 × 1016 cm–3. (a) what is the conductivity type (n-type or p-type) of this film? (b) what are the equilibrium electron and hole densities at 300 k and 600 k? (c) why does the mobile carrier concentration increase at high temperatures? (d) where is the fermi level located if t = 600 k?

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
