Large-Scale Simulations of a-Si:H: The Origin of Midgap States Revisited

Wanda Andreoni, Alessandro Curioni

Large-scale classical and quantum simulations are used to generate a-Si: H structures. The bond-resolved density of the occupied electron states discloses the nature of microscopic defects responsible for levels in the gap. Highly strained bonds give rise ...

Guided Bloch Surface Waves on Ultrathin Polymeric Ridges

Olivier Martin, Hans Peter Herzig, Tristan Sfez, Daniele Brunazzo, Francesco Michelotti

We present a direct evidence of Bloch surface waves (BSWs) waveguiding on ultrathin polymeric ridges, supported by near-field measurements. It is demonstrated that near-infrared BSWs sustained by a silicon-based multilayer can be locally coupled and guided ...
