碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 91 === In the last century, great progress in technology made it possible to use more resource of nature in nano scale systems. Abilities to manufacture and control micro size devices quantum heterostructures such as quantum dots have been developed for various nanotechnological applications. This paper applies the principle of quantum fluid dynamics to describe energetic structures, emission flow characteristics and the effective working region in particle emission flow field to provide basic information required for the design of quantum dots. The quantum potential consists of diffusion kinetic energy and dilatation energy of quantum flow due to non-uniform distribution of probability density plays a crucial role the energy exchange and transmission in nanosystems. Quantum energy of particle emission flow is related to kinetic energy, external potential and quantum potential characterized by quantum potential coefficient in nanosystems. The empirical law of quantized energy is obtained in terms of central potential, kinetic energy, and quantum potential evaluated at the emission surface, and the forbidden band of the eigenvalue energy is discussed and applications of this special quantum phenomenon in quantum communication technology are suggested.
