Abstract:
Method for growing carbon nanotubes having a determined chirality, comprising the steps of fragmentation of at least one initial carbon nanotube (30) having a determined chirality with obtainment of at least two portions, or seeds, of carbon nanotube, each one having one free growth end (32); supply of atoms of carbon (33) with autocatalyst addition of the atoms of carbon (33) at the free end (32) of each portion of nanotube (30) to determine an elongation, or growth, of the nanotube (30).
Abstract:
Described herein are a molecular memory obtained using DNA strand molecular switches and carbon nanotubes, and a manufacturing method thereof. In particular, the nonvolatile memory is manufactured according to an architecture that envisages the use of carbon nanotubes as electrical connectors and DNA strands as physical means on which to write the information. In other words, the nonvolatile memory is made by means of a set of molecular DNA strand switches, the addressing of which is controlled by molecular wires made up of carbon nanotubes.
