Directed Self-Assembly of Block Copolymer, No1
/Description The PS-rich and neutral PS-b-PMMA block copolymer (BCP) films were spin coated on the neutral random copolymer hydroxyl-terminated PS-r-PMMA layers grafted on the native oxide and 50 nm thick PECVD amorphous silicon oxide layers. Relationship between the grafting density of BCP and surface density of hydroxyl moiety on silicon oxide is discussed. Furthermore, optimization of anneal...
متن کاملBlock copolymer self-assembly–directed synthesis of mesoporous gyroidal superconductors
Superconductors with periodically ordered mesoporous structures are expected to have properties very different from those of their bulk counterparts. Systematic studies of such phenomena to date are sparse, however, because of a lack of versatile synthetic approaches to such materials. We demonstrate the formation of three-dimensionally continuous gyroidal mesoporous niobium nitride (NbN) super...
متن کاملMulticomponent nanopatterns by directed block copolymer self-assembly.
Complex nanopatterns integrating diverse nanocomponents are crucial requirements for advanced photonics and electronics. Currently, such multicomponent nanopatterns are principally created by colloidal nanoparticle assembly, where large-area processing of highly ordered nanostructures raises significant challenge. We present multicomponent nanopatterns enabled by block copolymer (BCP) self-asse...
متن کاملBlock copolymer self-assembly for nanophotonics.
The ability to control and modulate the interaction of light with matter is crucial to achieve desired optical properties including reflection, transmission, and selective polarization. Photonic materials rely upon precise control over the composition and morphology to establish periodic interactions with light on the wavelength and sub-wavelength length scales. Supramolecular assembly provides...
متن کاملRule-based Directed Self-assembly of Circuit-like Block copolymer Patterns
Templated self-assembly of block copolymers using topographic templates is attractive because it can generate dense nanoscale patterns over a large area with a periodicity down to 10 nm. In our previous work, regular patterns were achieved by using a polystyrene-bpolydimethylsiloxane (PS-b-PDMS) block copolymer and topographic templates . However, more complex block-copolymer patterns required ...
