Ap-n step junction in si has 1018 cm-3 net acceptors on the p side and 1014 cm-3 net donors on the n side. assume t = 300k, ni = 1.5 x 1010cm-3, find (a) the built-in potential and (b) extent of depletion region on n and p side. (c) explain how the built-in potential is related to the fermi level and what happens to vbi as a function of temperature in the range 30k to 500k.

answer: a. same unit

explanation:

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
