2-D Nanonets: from nanostructured material to highly promising macroscale functional devices
Randomly oriented nanowire (NW) network, also called nanonet (NN), is a novel semiconducting nanostructure which is electrically active, transparent, fault tolerant and readily functionalized. We strongly believe that such original network will open the way for an easy connection from nanostructure to macroscale applications. Several important achievements motivate us to go further in our research in order to put in evidence the NN originality: firstly, the material synthesis with simple, versatile, reproducible and low-cost technique; secondly, the sintering process for Si nanonets, patented by our group, which makes the NN conducting though the NW/NW junctions and stable in air for several years; finally and the most important breakthrough, the very recent successful integration of NN into highly performant field-effect transistors (FETs) via standard microelectronic technology. For example, the SiNN-FETs exhibited high ION/IOFF ratio as large as 105-106, good subthreshold slope and particularly reproducible performances from one device to another.
With this talk, I will explain the state of the art of nanonets, the fabrication method we are developing and the different material we are exploring. In particular, I will showcase our outstanding achievements with Si nanonets.
Céline Ternon is associate professor at Grenoble INP and member of Micro and Nanotechnology Federation (FMNT) labs since 2003 in France. She works in the field of nanomaterials and nanotechnologies. Her research interest lies at the interface between material science and device application, with a particular interest for the field of biosensing. One of her main objective is to develop new processes allowing the easy manipulation and integration of the nanomaterials into devices. In 2010, she launched a new activity based on semiconducting randomly oriented nanowire networks.
