Nowadays, carbon nanomaterials are increasingly garnering attention as the next generation of semiconductor materials. Notably, graphene and carbon nanofibers (CNFs) have emerged as pivotal players in the semiconductor domain, owing to their remarkable electrical, mechanical, and thermal properties, coupled with their distinctive structural attributes.
Graphene, characterized by its two-dimensional single-layer structure of densely packed carbon atoms, boasts unparalleled electrical conductivity. This positions it for significant potential in applications like highfrequency electronic devices and sensors. Furthermore, its transparency and flexibility pave the way for innovative advancements in flexible electronic devices and display technologies, rejuvenating the electronics industry’s potential. CNFs, celebrated for their nanoscale diameter and exceptional mechanical attributes, carve a niche for themselves in material science. Their superior conductivity heralds vast opportunities, especially in realms such as conductive fibers and flexible circuitry. Within the spectrum of synthesis techniques, Chemical Vapor Deposition (CVD) emerges as a standout method, particularly for producing highquality graphene films and CNFs.
This dissertation delves into the CVD preparation, performance characterization, and subsequent applications of these materials, particularly in electromagnetic (EM) and ultraviolet (UV) optics. Specifically, the research encompasses:
In essence, this research centers on graphene and CNFs, exploring their potential in the realm of EM and UV optics and offering insights based on their intrinsic properties.
