EurekAlert  April 15, 2020 Low density materials can control plasma properties of laser absorption, which can enhance quantum beam generation. Researchers in Japan propose a target source based on a hollow sub-millimeter microcapsule fabricated from polyelectrolyte cationic and anionic surfactant on air bubbles. The lightweight microcapsules acted as a scaffold for surface coating by tin (IV) oxide nanoparticles. In a proof of concept study the laser conversion efficiency at 13.5 nm 2% bandwidth from the tin-coated microcapsule (0.8%) was competitive compared with bulk tin (1%). According to the researchers microcapsule aggregates could be utilized as a potential small scale/compact EUV source […]
