Stretchable Nanoparticle Films

Flexible and stretchable electronic and opt-electric devices have a lot of interest and applications including light-emitting devices, solar photovoltaics sensors, health monitoring devices and communication technologies. However, to date there are few to no studies on the mechanical behavior of nanocrystal (NC) films on stretchable substrates.  This study focused on experimental and theoretical point of view of Nano structure materials deposition on soft and flexible substrates. Particularly,  silicon nanoparticle growth on polydimethylsiloxane (PDMS) as a flexible substrate has been investigated. This effort has been developed to transfer current knowledge of mechanical instabilities arises from NCs deposition on elastomer substrate to a new level of application and related physical properties  such as film porosity, NC size dependence and thickness variation.
