Quantum confinement,nanotechnology, quantum dots, energy gap. One method to increase the gap size in silicon involves altering the size of the excitation. suppose we consider an optical gap, egap, as the difference between the highest filled and lowest empty states for a system confined in a sphere of size r. The quantum confinement effect is observed when the size of the particle is too small to be comparable to the wavelength of the electron.to understand this effect we break the words like quantum and confinement, the word confinement means to confine the motion of randomly moving. From pl results, the presence of mns shells. For an object in a conservative field of force, a region in which the term potential well derives from the appearance of the graph that represents the dependence of the potential energy v of a particle in a force field on the particle's position in space. • confinement produces discreteness of allowed electron energies giving rise to.
