  • Patent number: 7635867
    Abstract: A nanotube array and a method for producing a nanotube array. The nanotube array has a substrate, a catalyst layer, which includes one or more subregions, on the surface of the substrate and at least one nanotube arranged on the surface of the catalyst layer, parallel to the surface of the substrate. The at least one nanotube being arranged parallel to the surface of the substrate results in a planar arrangement of at least one nanotube. Therefore, the nanotube array of the invention is suitable for coupling to conventional silicon microelectronics. Therefore, according to the invention it is possible for a nanotube array to be electronically coupled to macroscopic semiconductor electronics. Furthermore, the nanotube array according to the invention may have an electrically insulating layer between the substrate and the catalyst layer.

  • Patent number: 7265376
    Abstract: A nonvolatile memory cell, memory cell arrangement, and method for production of a nonvolatile memory cell is disclosed. The nonvolatile memory cell includes a vertical field-effect transistor (FET). The FET contains a nanoelement arranged as a channel region and an electrically insulating layer. The electrically insulating layer at least partially surrounds the nanoelement and acts as a charge storage layer and as a gate-insulating layer. The electrically insulating layer is arranged such that electrical charge carriers may be selectively introduced into or removed from the electrically insulating layer and the electrical conductivity characteristics of the nanoelement may be influenced by the electrical charge carriers introduced into the electrically insulating layer.
