Abstract
A new substrate pretreatment for the synthesis of diamond with hot filament chemical vapor deposition (HFCVD) is reported. The substrate was prepared by galvanizing a thin layer of iron on porous silicon. Sphere-like diamond was observed, whose surface was embedded by certain surface morphology of diamond. Further more, several high diamond towers were detected, which consist of dozens of diamond spheres. SEM and Micro-Raman spectroscopy confirm the result.
