Covalent bonding
Lifetime
Recombination
Thermal energy E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is C. Recombination.
Recombination is the merging of a free electron and a hole. This can happen when an electron falls into an empty energy state in the valence band. This process releases energy,
which can be in the form of light, heat, or sound.Covalent bonding is a type of chemical bond that involves the sharing of electrons between atoms. Lifetime is the amount of time that an object exists before it decays or disappears. Thermal energy is the energy that an object has due to its temperature. None of these options are the merging of a free electron and a hole.
