Photonic integrated circuits (PICs) based on lithographically patterned waveguides provide a scalable approach for manipulating photonic bits, enabling seminal demonstrations of wide range technologies with desired complexity and stability. While the next generation applications such as ultra-high speed optical transceivers, neuromorphic computing terabit-scale communications demand further low...

a r t i c l e i n f o The composite film of carbon nanotubes and silicon carbide nanowires was synthesized directly on the silicon substrate by the catalyst-assisted method. The carbon nanotubes crimped together decorated with silicon carbide nanowires covering the whole substrate. The appropriate amount of aluminum powders is a crucial factor to achieve the composite film. The composite film e...

Photoelectron spectroscopy (PES) is combined with density functional theory (DFT) to study the monochromium carbide clusters CrCn- and CrCn (n = 2-8). Well-resolved PES spectra were obtained, yielding structural, electronic, and vibrational information about both the anionic and neutral clusters. Experimental evidence was observed for the coexistence of two isomers for CrC2-, CrC3-, CrC4-, and ...

The dewetting of ultrathin silicon layers, induced by the thermal budget, is an issue to develop SOI-based technology. This study aims at demonstrating the effect of the strain on the dewetting mechanism [1] (Figure 1). For that purpose, we present the results obtained on (001) oriented ultrathin (<11 nm) silicon layers on silicon dioxide (SOI). Both stress-free and strained (s-SOI) films fabri...
