A Novel Technique for Purifiction and Segregation of CNT Using Inkjet Technology

Chaves J.S., Chaves S., Chaves J.S., Chaves S., Mangir T., California State University Long Beach, US

Since Carbon Nanotubes (CNT) were discovered in the early 90’s a whole new research field has evolved. CNTs have many properties that make them desirable for the construction of nano-scale Electronics. One area that is [...]

Precision Placement and Integration of Individual Carbon Nanotubes in Nanodevices by Fountain-Pen controlled Dielectrophoresis

Schwamb T., Schirmer N., Poulikakos D., ETH Zürich, CH

Herein, we present a novel fabrication method for the integration of special nanoparticles such as nanowires and carbon nanotubes into NEMS/MEMS. To this end, we combined the dielectrophoretic deposition of carbon nanotubes with a fountain-pen [...]

Templated Self-Assembly of 5 nm Gold Nanoparticles

Ocola L.E., Lin X-M., Argonne National Laboratory, US

Combining top-down electron beam lithography and bottom-up colloidal chemical assembly can potentially lead to large scale patterning of nanocrystals on arbitary substates. Our approach consists of fabrication of templates from hydrogen silsesquioxane (HSQ) on treated [...]

A Novel Self-Assembled and Maskless Technique for Highly Uniform Arrays of Nano-Holes And Nano-Pillars

Wu W., Dey D., Memis O.G., Katsnelson A., Mohseni H., Northwestern University, US

We present a low-cost and high-throughput process for realization of two-dimensional arrays of deep sub-wavelength features using a self-assembled monolayer of HCP silica and polystyrene microspheres and well-developed photoresist lithography. This method utilizes the microspheres [...]

DNA-guided Assembly of Organized Nano-Architectures

Gang O., Maye M.M., Nykypanchuk D., Xiong H., van der Lelie D., Brookhaven National Laboratory, US

Incorporation of DNA into nano-object design provides a unique opportunity to establish highly selective and reversible interactions between the components of nanosystems. Assembly approaches based on the nano-object’s addressability promise powerful routes for creation of [...]

Electric Field Assisted Assembly of Perpendicular Oriented ZnO Nanorods on Si Substrate

Lupan O., Chow L., Chai G., Park S., Schulte A., University of Central Florida, US

Self-assembly of nanoarchitectures has attracted high interest driven by the demands of technology and engineering. Chemical and electric field assisted assembly offer a great opportunity in creation of heterostructures in multicomponent systems and in manufacturing [...]

Self-assembly of Functional Groups inside High Aspect Ratio Silicon Nanopores

Moghaddam S., Masel R., Shannon M., UIUC, US

A novel technique has been developed to assemble molecules with functional end groups inside pores of a nanoporous silicon membrane. A 20-um thick p-doped silicon membrane was anodized in HF electrolyte to produce 5-7 nm [...]

UV-NIL with optimal droplets

Sirotkin V., Svintsov A., Zaitsev S., IMT RAS, RU

A homogeneous residual layer thickness in nanoimprint lithography (NIL) is a serious problem in step and flash (UV-)NIL. Improvement of thickness homogeneity could be expected from optimized size of droplets at resist dispensing in case [...]

New Method for large Area NIL – SCIL

van Eekelen J., Weixlberger J., Suss MicroTec Lithography, DE

A new imprint technology for sub-50nm patterning will be introduced, bridging the gap between small rigid stamp application for best resolution and large area soft stamp usage with usual limited printing resolution below 200nm - [...]

Bimodal Macro- Mesoporous Silica Network

García Martínez J., Abellán G., Carrillo A.I., Linares N., University of Alicante, ES

Herein we described the synthesis of novel kind of silica materials prepared at room temperature in the presence of cationic surfactant, more specifically a quaternary amine (tallow tetraamine) to obtain silica-based materials with attractive properties, [...]
