Aligned Carbon Nanotube Patterning Via Dry Contact Transfer Printing

The approach of transferring CNT thin films from one surface to another via a soft lithography technique suffers from limited ability to achieve good adhesion of the CNT films to the transferred substrate and imprecise alignment of the CNT patterns. A transfer technique  that can be scaled to large area with high throughput processing at low temperature is being reported in this paper, demonstrating a scalable means to create aligned CNT thin film patterns on both rigid and flexible substrates.

Chip schematic. (a) illustrates the bias electrode used for applying the bias potential from the arbitrary function generator and the counter electrodes, which are capacitively coupled to the conductive substrate except for one, which is directly coupled to the ground. Inset (b) shows in detail the finger electrodes in yellow, over which the two-dimensional graphene nanostructures will bridge. The cross section of the finger electrode gap is depicted in (c).

High-yield dielectrophoretic assembly of two-dimensional graphene nanostructures

The serial mechanical exfoliation method available can not be used for the assembly of graphene in the large scale. In this process, deposition of ultrathin few-layer (three to ten) graphene oxide, with parallel and controllable assembly, by dielectrophoresis between prefabricated electrodes has been demonstrated.

Pulse-reversed electrodeposition with QCM monitoring to make magnetic nanowires in a nanotemplate

Cobalt nanowires with high perpendicular magnetic anisotropy are formed in a diblock copolymer film template using a pulse-reversed voltage with QCM monitoring.  This in situ monitoring system along with the pulse-reversed field enables new control over the magnetic crystal growth.

Fabrication of a nanoporous template from a diblock copolymer film - neutral brush

A perpendicular orientation of cylindrical microdomains in diblock copolymer thin films is achieved by control over polymer-surface interactions. The block which forms cylindrical microdomains is removed by UV exposure and a chemical rinse to yield a nanoporous polymer film. The porous film can be used as a template for electrodeposition of metal nanodots or as a mask for reactive ion etching.
