Biased sip-n junction a si p-n junction with area of 0.001 cm* is formed with an acceptor concentration of na 1x1015 cm3 on the p-side and a donor concentration of na- 1x10" cmon the n-side. calculate at 300 k (a) the diffusion voltage vd (b) the space charge width at equilibrium and with zero bias (c) the current with forward bias of 0.5 ev. assume that the current is diffusion dominated. the electron and hole mobilities are ln-1500 cm2/(vs) and μ,-450 cm2/(vs), the recombination lifetimes are τη-τp-2.5 ms. do electrons or holes carry most of the current, and why? if you want to double the electron current, what do you need to do?

i believe the answer is b.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
