Maritza Mujica was lead author on a manuscript titled “The Geode Process: Hollow Silica Microcapsules as a High Surface Area Substrate for Semiconductor Nanowire Growth” that was recently accepted to ACS Applied Nano Materials. The Geode process is inspired by the geological rock formation of the same name. Hollow silica microcapsules lined with the metal nanoparticles that seed nanowire growth are first produced with a scalable emulsion templating technique. A dried microcapsule powder is then loaded into a chemical vapor deposition reactor where it provides a surface area for nanowire growth several orders of magnitude larger than would be possible on conventional, flat substrates. Congrats to Maritza and all her co-authors on this initial demonstration!
