Optical and Electrophysical Properties of Thin Anisotropic Films Based on Carbyne Stabilized by Gold Particles

This study considers the optoelectrical properties of thin films composed of linear carbon stabilized by gold nanoparticles. We explore the unique anisotropic behaviors exhibited by these films and their dependence on the degree of structural ordering. The fabrication process includes the use of colloidal systems, with a focus on the laser-induced fragmentation of gold nanoparticles within a carbon matrix. Our findings reveal that applying a potential difference significantly alters the absorption characteristics of the films, particularly enhancing absorption at frequencies associated with short linear chains, while also inducing a transparency effect in the visible range. The introduction of electrons into the carbon matrix is identified as a key factor influencing these optical properties, drawing parallels to existing literature on resonance pumping phenomena. Additionally, the results indicate a considerable modification of the Schottky barrier at the semiconductor-metal interface due to structural orientation. This research provides insight into the potential applications of these materials in optoelectronic devices and highlights the importance of structural characteristics in tailoring their properties.
