A silicon specimen is made into a p-type semiconductor by dropping, on an average, one indium atom per silicon atoms. If the number density of atoms in the silicon specimen is
atoms
then the number of acceptor atoms in silicon per cubic centimeter will be
Number density of atoms in silicon specimen =silicon atoms, so total number of indium atoms doped per atoms, so total number of indium atoms doped per
of silicon will be

5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K
A capacitor is made of two square plates each of side 'a' making a very small angle
A solution of m-chloroaniline, m-chlorophenol and m-chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of NaHCO3 to give fraction A. The leftover organic phase was extracted with d
