There is a moscap structure with n-type si and nd = 10¹⁶/cm³ and vfb = 0. let the m-o-s direction be the x-axis, x=0 at the oxide-si interface and x increases as it goes into the bulk of the si. now define the band bending ψ(x) = − " # [ei(x) – ei (bulk)].
(a) how do you determine accumulation, depletion and inversion from ψ(0)?
(b) express n(x), p(x) in terms of ψ(x) in the si.
(c)assuming complete ionization, express the poisson’s equation in the si in terms of ψ(x).

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

no

explanation:

no i dont know how to solve this you should probably try to google the answer
