A p-type semiconductor is (i) a silicon crystal doped with arsenic impurity (ii) a silicon crystal doped with aluminium impurity (iii) a germanium crystal doped with boron impurity (iv) a germanium crystal doped with phosphorus impurities.
Pure silicon doped with phosphorus is :
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 ?
Pure silicon doped with phosphorus is:
Account the following : Silicon is an insulator but silicon doped with phosphorus acts as a semiconductor.
silicon doped with electron rich impurity forms ………. .
An intrinsic semiconductor is doped with arsenic how will the energy gap change in semiconductor
