A perfect crystal of silicon is doped with some elements as given in the options. Which of thses options show n-type semiconductors-

In an ideal crystal, the entropy of the constituents at absolute zero temperature (0K) is zero. However, the crystals generally suffer from certain defects also called imperfections They may be both electronic and atomic in nature. The atomic imperfections may be stoichiometric (Schottky and Frenkel defects) or non-stoichiometric (metal excees and metal deficiency defects). In addition to these, there are impurity defects which are caused by the addition of certain impurities of metals and this is known as dopping. The dopping leads to semi conductors which may be either n-type or p-type in nature. Silicon doped with arsenic is

To get n -type doped semiconductor, impurity to be added to silicon should have the following number of valence electrons
