Double wall carbon nanotubes (DWCNTs) were mass-produced by pyrolizing C2H2 at the temperature range of 900–1100 °C on a floating iron catalyst with sulfur promoted. Our experiments indicated that the growth of DWCNTs was strongly dependent on the

We present Interference Assisted Lithography (IAL) as a promising and cost-effective solution for extending lithography. IAL achieves a final pattern by combining an interference exposure with a trim exposure. The implementation of IAL requires that

We demonstrated a record-high-intensity bowtie nano-aperture vertical-cavity surface-emitting laser (VCSEL) with near-field spot size of 65 nm. The bowtie aperture VCSEL is very promising to realize ultradense near-field optical data storage.
