The study of normalized exciton binding energy is essential for understanding the electronic and optical properties of low-dimensional nanostructures. In this work, we investigate the normalized exciton binding energy in cylindrical nanostructures, taking into account the effects of longitudinal optical phonons (LOP). Using the effective mass approximation in conjunction with a variational method, we investigate how the size of the nanostructure and the presence of a finite barrier potential affect excitonic behavior. Our results emphasize the interplay between quantum confinement and potential confinement in the presence of LOP-interactions, revealing a significant impact on the excitonic properties. These findings have important implications for the design and performance of optoelectronic devices, and we discuss their potential applications in advanced photonic and electronic technologies.

摘要

The study of normalized exciton binding energy is essential for understanding the electronic and optical properties of low-dimensional nanostructures. In this work, we investigate the normalized exciton binding energy in cylindrical nanostructures, taking into account the effects of longitudinal optical phonons (LOP). Using the effective mass approximation in conjunction with a variational method, we investigate how the size of the nanostructure and the presence of a finite barrier potential affect excitonic behavior. Our results emphasize the interplay between quantum confinement and potential confinement in the presence of LOP-interactions, revealing a significant impact on the excitonic properties. These findings have important implications for the design and performance of optoelectronic devices, and we discuss their potential applications in advanced photonic and electronic technologies.
