dc.description.abstract Propunem o tehnologie electrochimică cost-efectivă în doi Pași la temperature camerei pentru obținerea nanomembranelor de Au. Un film subțire de Au cu grosime mai mică de 100 nm a fost depus prin depunerea electrochimică din impulsuri pe un substrat de GaAs în prima etapă, urmată de anodizare pentru a introduce porozitatea în substratul de GaAs sub filmul de Au. La parametrii optimizați de anodizare, are loc desprinderea filmului de substrat. Filmul de Au constă dintr-un monostrat de nanoparticule de Au cu diametrul 20-30 nm și s-a dovedit a fi flexibil și extensibil, cu posibilități de a transfera nanomembranele preparate pe diferite substraturi. en_US
dc.description.abstract Herein, we propose a room-temperature two-step cost- effective electrochemical technology for the preparation of free-standing Au nanomembranes. A thin Au film with thickness less than 100 nm was deposited by pulsed electroplating on a GaAs substrate in the first step, followed by anodization in the second technological step to introduce porosity into the GaAs substrate underneath the Au film. At optimized parameters of anodization, detachment of the film from the substrate occurs. The gold film consist of a monolayer of Au nanoparticles 20-30 nm and proved to be flexible and stretchable, with possibilities to transfer the prepared nanomembranes to various substrates. en_US
