Infrarot Absorption von Black Silicon

20.11.2014, 10:00, Erwin-Schrödinger-Hörsaal, Boltzmanngasse 5, 5. Stock, 1090 Wien


Black silicon hyperdoped with heavy chalcogen atoms via femtosecond-laser irradiation exhibits strong broadband, sub-bandgap light absorption.
We have measured the absorption to wavelengths up to 14 μm using Fourier transform infrared spectroscopy.
We have also studied sulfur-, selenium-, and tellurium-hyperdoped Si before and after annealing
