A hitherto unseen SEM in operando observation method is devised and a clear relation is established between voids evolution and the one of the electrical resistance. Expand
Fabrication and characterization of three-dimensional silver/air inverted opal photonic crystals
Photonic crystals made from noble metals such as silver are an interesting class of material for many applications such as chemical sensing, solar cells or photonics. Their fabrication suffers from a… Expand
Scalable chemical synthesis of doped silicon nanowires for energy applications.
When used in symmetric supercapacitor devices, 1% P-doped SiNWs exhibit an areal capacity of 0.25 mF cm-2 and retention of 80% of the initial capacitance after one million cycles, demonstrating excellent cycling stability of the SiNW electrodes in the presence of organic electrolytes. Expand
Nucleation and Chemical Transformation of RuO2 Films Grown on (100) Si Substrates by Atomic Layer Deposition
We describe the formation of RuO2 thin films grown using atomic layer deposition (ALD) on (100) Si substrates from Ru(EtCp)2 and O2, and the subsequent influence of annealing temperature and… Expand
