Abstract
The ability of high-energy hot electrons to overcome potential barriers and transport energy rapidly makes them a key factor in the development of breakthrough technologies. In medical applications, the generation of hot electrons enables the integration of diagnostic and therapeutic functions at the nanoscale. Hot electrons allow for the intensification of photochemical transformations driven by light energy, bypassing the high-temperature requirements of traditional catalysis. The capture and transport of plasmonic hot electrons facilitate the creation of ultrafast optical switches and light modulators operating on picosecond and femtosecond timescales for high-speed data transmission systems, as well as current sources with high-speed optical modulation for vacuum electronics. This paper presents the results of a search for efficient plasmonic nanoparticles (nanorods and bipyramids) characterized by enhanced hot-electron generation and an improved energy-efficiency balance.
