A hole is a seat of positive charge which is produced when an electron breaks away from a covalent bond in a semiconductor. Class 12 Physics Chapter 14 Semiconductor Electronics Session 2024-2025.
The four valence electrons in carbon are in the second orbit but in silicon these are in third orbit. Hence, energy required to take out an electron from carbon is Eg = 5.4 eV but for silicon Eg = 1.1 ...
In both these processes total binding energy of products is more than the total binding energy of reactants. As a result energy is released which is equal to the difference between binding energy of products and binding energy of reactants.
Of course in a nuclear reaction both the number of protons and neutrons (i.e., the mass number as well as atomic number) remains conserved, yet total mass of products is not same as the total mass of reactants. There is ...
