In doped semiconductor one dopent atom is kept typically for how many silicon atoms ?

A Si specimen is made into p -type semiconductor by doping on an average one indium atom per 6 xx 10^7 silicon atoms. If the number density of atoms in Si be 6 xx 10^28//m^3 , the indium atoms per cm^3 are

In the structure of silica, each silicon atom is bonded to how many oxygen atoms ?

A p-type semiconductor is obtained by doping silicon with

In the structure of silica , each silicon atom is vbonded to bow many oxygen atoms ?

In the structure of silica , each silicon atom is vbonded to bow many oxygen atoms ?

Give reasons Silicon doped with phosphorus, gives an n-type semiconductor, while p-type semiconductor is obtained when silicon is doped with gallium.

Give reasons Silicon doped with phosphorus, gives an n-type semiconductor, while p-type semiconductor is obtained when silicon is doped with gallium.

Define the term doping. Pure silicon is an insulator. Silicon doped with phosphorus is a semiconductor. Silicon doped with gallium is also a semi-conductor. What is difference between the two types of semi-conductors ?
