“…Here we present a systematic study of the synthesis of lateral templates with various pore sizes, varying from 5 to 100 nm that can be used to grow single wall carbon nanotubes (SWNTs) and semiconductor nanowires (NWs). On the other hand, we have already shown the potential advantages (particularly in terms of mask count) of growing silicon nanowires inside lateral PAA templates for active matrix-type applications such as displays or x-ray image sensors [13,14]. Figure 1 shows the general scheme that we use to synthesize PAA membranes having their pore direction parallel to the surface of the substrate.…”

Confined lateral alumina templates are fabricated with different pore sizes by changing the acid electrolyte and the anodization voltage. The control of the number of pore rows down to one dimension is also achieved, by controlling the thickness of the starting aluminum film as well as the anodization voltage. We observe that the mechanism of pore formation in the lateral regime is very similar to that in the classical vertical situation.

“…Finally, we would like to point out that lateral membranes would also simplify the fabrication process of thin film transistors used in active matrix backplanes for addressing flat panel displays. In particular, only 4 masks would be needed for the fabrication of an active matrix liquid crystal display backplane (37), a mask number competitive with that of the current amorphous silicon technology.…”

We present some of our first experiments on the controlled growth of silicon nanowires and carbon nanotubes in lateral porous alumina templates synthesized by anodic oxidation of Al thin films. Under adapted chemical vapor deposition growth conditions, and using the vapor-solid-liquid mechanism, the pores of the lateral membranes can be partially filled with silicon nanowires or carbon nanotubes, yielding a composite thin film of parallel-organized nano-objects. Such composite thin films can be further tailored and shaped by classical microelectronic-type tools and processes, in order to fabricate electronic devices.

“…This deposition method, patented [24,25], allowed fabricating wafers of CNTFETs with reproducible performances and with on/off current ratios of at least three orders of magnitude [26]. In order to perform a selective sensing we decided to fabricate an array of sensors composed by different metals as source and drain contacts (see patent [27]).…”

The dynamic spray-gun deposition method was developed in 2006 to fabricate field effect transistors based on random arrays of carbon nanotubes (CNTs) field effect transistors for gas sensing applications. Thanks to this deposition method, we were able to fabricate hundreds of operational devices in a reproducible way that were integrated in electronic chips. Following this first implementation, we decided to widen the application of the deposition technique to the field of Energy and specifically to the fabrication of supercapacitors. In this context, we demonstrated in 2012 the fabrication of nanostructured electrodes for supercapacitors, using mixtures of graphene/graphite and CNTs increasing the device capacitance and the power delivered of a factor 2.5 compared to CNT based electrochemical-double-layer-capacitors. Indeed, with high quality graphene we could reach a value of around 100 W Kg −1 . This value is extremely promising also considering that it has been obtained with an industrially suitable technique. This dynamic spray-gun deposition has been also exploited for the fabrication of resistance based random access memories, making use of thin layers of graphene oxide and of oxidized carbon nanofibers. In the first case, 5000 cycles of 'write' and 'read' phases were demonstrated. These results pave the way for the fabrication of very low cost memories that can be embedded in smart-cards, patches for health monitoring (e.g. diabetes), ID cards, RFID tags and more generally smart packaging. Finally we are also working on the utilization of this technique for the fabrication of layers for electro-magnetic interference shielding application. Thanks to a new machine with four nozzles, developed within the frame of the Graphene Flagship project, we are able to deposit four different nanomaterials at the same time or alternatively on a large surface (30 cm×30 cm) creating specific nano-structuration and therefore ad hoc architectures allowing the smart absorption of specific frequencies (e.g. X-band). All these applications demonstrate the extreme versatility of this technique that constitutes a real breakthrough for exploiting the nanomaterials characteristics in real devices, using an industrial suitable fabrication method that can be implemented using roll-to-roll technique.
