WebApr 11, 2024 · Due to the cylindrical symmetry, the degree of freedom of the electron is reduced from 3 to 1. We assume that the core material is made of Al Ga As with a radius of a, covered by GaAs shell material with a radius of b. The core/shell structure is embedded into a matrix material with a wide band gap. The Bessel function is a generalization of the sine function. It can be interpreted as the vibration of a string with variable thickness, variable tension (or both conditions simultaneously); vibrations in a medium with variable properties; vibrations of the disc membrane, etc. Bessel's equation arises when finding separable … See more Bessel functions, first defined by the mathematician Daniel Bernoulli and then generalized by Friedrich Bessel, are canonical solutions y(x) of Bessel's differential equation The most important … See more Because this is a second-order linear differential equation, there must be two linearly independent solutions.
