Low Dimensional Optoelectronic Devices enabled by Vacuum and Plasma Technologies

Abstract

The need for energy-efficient technologies is critical for confronting urgent environmental challenges. This Ph.D. thesis explores the development of nanostructured optoelectronic devices with enhanced efficiency, durability, and functionality using plasma and vacuum technologies. It focuses on synthesizing and integrating low-dimensional nanostructures, such as 1D nanowires, nanotubes, core@(multi)shell systems, and nanowalls, through multistep soft-template methods and glancing angle deposition (GLAD). These materials were integrated into photovoltaic devices and photodetectors, demonstrating improved stability and multifunctionality. The research not only highlights the transformative potential of vacuum and plasma technologies in creating advanced optoelectronic devices but also paves the way for more sustainable, energy-efficient technologies.
