A Path to 8 nanometer or Narrower Self Assembled Lithography

Nano Letters – A Path to Ultranarrow Patterns Using Self-Assembled Lithography The templated self-assembly of block copolymer (BCP) thin films can generate regular arrays of 10−50 nm scale features with good positional and orientational accuracy, but the ordering, registration and pattern transfer of sub-10-nm feature sizes is not well established. Here, we report solvent-annealing and …

New Photonic Material Brings 2000 Gigahertz All-optical Switching and Computing Closer

A class of molecules whose size, structure and chemical composition have been optimized for photonic use could provide the demanding combination of properties needed to serve as the foundation for low-power, high-speed all-optical signal processing. All-optical switching could allow dramatic speed increases in telecommunications by eliminating the need to convert photonic signals to electronic signals …
