Variables Used
Total Energy of a Particle in Quantum Dot - (Measured in Joule) - Total Energy of a Particle in Quantum Dot is the sum of Band gap energy, Confinement energy and Coulombic or bound exciton energy.
Band Gap Energy - (Measured in Joule) - The Band Gap Energy is the minimum amount of energy required for an exciton to break free of its bound state.
Confinement Energy - (Measured in Joule) - Confinement Energy in the particle in a box model is also used in modeling the exciton. Variance of particle size allows for control of the confinement energy.
Coulombic Attraction Energy - (Measured in Joule) - Coulombic Attraction Energy is the energy which holds together the ionic compounds.
