Abstract
The explosive abilities of porous silicon (pSi) provide an alternative to existing carbon based explosives, in addition to the possibilities of explosions on a nanoscale. Here, an investigation into these explosive properties is conducted, by introducing an oxidiser onto freshly etched pSi with varying pore sizes. Explosions are triggered via the application of an electric spark. Light output and spectral data are collected to characterize the exxplosion. The energy output is observed via Differential Scanning Calorimetry (DSC), and surface images collected using SEM and AFM.
