Substrate arrangement. a Image of eight Si(100) substrates placed onto the ceramic insert in the quartz boat. The metal housing and the white isolation material of the furnace can be seen on the right-hand side. The blue frame indicates the four substrates coated with TiO2 catalyst nanoparticles, and the green frameindicates four pristine substrates without catalyst. b Sketch of the substrate arrangement. Two substrates with (blue) and without catalyst (green) are placed next to each other. The ceramic insert assures the position of the substrates remains unchanged
