ACHIVED RESULTS
The main achieved results concern the activity of modelling and simulation (WP3) and of fabrication and synthesis of the alumina membrane and of the CNTs and CNFs (WP4), according to the work-plan. The activity of WP2 (Requirement definition) and of WP5 (Experimental characterizations) have mainly supported the activities of WP3 and WP4. In the following the specific achievement and the main results are described. The obtained results concerning modelling and simulation (WP3) are in line with the schedules objectives.
The most important innovative results are in particular:
-
A new formulation of the no. of conducting channel of each carbon nano-tube shell, which is very general because it takes into account of any CNT possible configuration, and it allows overcoming limitation of existing formulations in the literature;
-
A new general formulation of the RF transmission line model of SWCNT and SWCNT bundles in any configuration;
-
A new generation formulation of the RF transmission line model of an MWCNT in both horizontal and vertical configuration;
-
A new equivalent single conductor model of an MWCNT, including new formulation of the effective quantum capacitance and kinetic inductance that include the effects of all intershell coupling capacitances and inductances.
A consistent number of publications produced by the consortium describe the obtained results. The main achievements concerning the activity of synthesis and fabrication are:
-
Production of two different types of alumina porous membranes with controlled geometry: membrane opened at both sides, and membranes directly grown over a silicon substrate;
-
Synthesis of MWCNTs with controlled diameter, number of walls and length inside the holes of the alumina membranes opened at both sides, without the use of a catalyst;
-
Production of arrays of Ni-nanodots to be used as catalyst for the growth of CNTs inside the holes of the alumina membrane over the silicon substrate and as catalyst for CNFs;
-
Synthesis of well aligned CNFs using Ni-nanotods with controlled diameter.
