Let a small quantity of phosphorus be doped into pure silicon. Will the resulting material contain same no. of total electrons as original pure silicon?

Will the resulting material contain the same number of total number of electrons as the original pure silicon ?

Explain doping of Silicon with Phosphorus.

A pure silicon crystal at absolute zero temperature behaves as

Silicon doped with electron rich impurity forms

A small metal ball of mass m is dropped in a liquid contained in a vessel , attains a terminal velocity v . If a metal ball of same material but of mass 8 m is droped is same liquid then the terminal velocity will be

Pure silicon should be doped with which of the foll. Impurity atoms to make a p-type semiconductor?

Same quantity of ice is filled in each of the two metal containers P and Q having the same size, shape and wall thickness but made of different materials. The containers are kept in identical surroundings. The ice in P melts completely in time t_1 , whereas that Q in takes a time t_2 . The ratio of thermal conductivities of the materials of P and Q is

A mixture of benzene and toluene contains 30% by mass of toluene. At 30^@C , vapour pressure of pure toluene is 36.7mm Hg and that of pure benzene is 118.2 mm Hg. Assuming that the two liquids form ideal silutions, calculate that total pressure and partial pressur eof each constituent above the solution at 30^@C .

A pure silicon crystal has 4 xx 10^28 atoms m^-3 . It is droped by 1ppm concentration of antimony. Calculate the number of electrons and holes n_i = 1.2 xx 10^16//m^3
