Creating 20Â nm thin patternable flat fire

In this study, we reported a novel method of creating a sustainable fire at nanoscale and in two dimensional patterns. We observed as high as 15 °C over 20 nm Pt/ Al2O3 layer (vertical thermal gradient >750 °C/μm or 750,000 °C/mm); when the vertical temperature difference is about 5 °C horizontal the thermal gradient is larger than 1.33 °C/μm (or 1330 °C/mm) along the surface.275
