Abstract
Si nanowires grown from TiSi <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> catalysts exhibit near-infrared photoluminescence (PL) from quantum-confined excitons in the Si. Temperature dependent studies highlight the differences between Si nanocrystals and nanowires, which allow for exciton diffusion
