The total current density in a semiconductor is given as constant and Jtop = -20 A / cm ^ 2. Total current density is the sum of the hole drift current density and the electron diffusion current densities. The hole density in the crystal is constant and p = 0.64 * 10 ^ 10 cm ^ -3. Electron density (to be written in x distance micrometer) is given as n (x) = 2 * 10 ^ 15 * e ^ (- X / L) cm ^ -3 and L = 20 micrometer. Since the diffusion coefficient of electrons is Dn = 26 cm ^ 2 / s and the mobility of the holes is n = p = 440 cm ^ 2 / Vs:
a) Find the variation of the electron diffusion current density
depending on the location and draw approximately by stating the
important values,
b) Find the variation of the electric field applied to the
semiconductor depending on the location and draw the approximate
values by drawing them approximately,
c) Find the variation of the hole drift current density depending
on the location and draw approximately by specifying the important
values.
I need quick answer please.Thank you

A 5.0 mm diameter proton beam carries a total current of 1.5mA. The current density in the proton beam, which increases with distance from the center, is given by J = Jedge(r/R), where R is the radius of the beam and Jedge is the current density at the edge. I calculated that 9.375 x 10^15 protons are delivered by the proton beam each second, but I do not know where to start in calculating the value of Jedge. I am...

The Hubble Constant, the density of the universe, and the
cosmological constant are all vital to the evolution of our
universe. Briefly discuss why each is so important -and- what would
happen if we tweaked each one up or down a little. Are there other
constants that are equally important? If so, which and why?
