Carbon nanotubes (CNTs) and semiconductor nanowires (NWs) are a new class of materials currently being studied within the context of molecular electronics. Because of their excellent characteristics, CNT- and NW-based transistors could become the workhorse of the post CMOS era. Since CNTs as well as Si or Ge NWs can be grown at low temperature and on non crystalline and non refractory substrates, they could certainly be used in the near future for TFT and active matrix backplane fabrication. However, the development of these materials is hampered by the general problems posed by their manipulation, their placement and their inplane organisation. In this paper, we first review the possible use of CNT random networks (that do not need to be organised) for the fabrication of thin film transistors (TFTs). We then present a new way of organising semiconductor NWs in a TFT, based on the use of lateral porous anodic alumina templates.
