U.S. Patent #7544546 – Formation of carbon and semiconductor nanomaterials using molecular assemblies

Share this post:

Carbon nanomaterials have long demonstrated great promise in enabling dramatically improved circuits and data storage devices. This patented invention describes a process that can be used to selectively position nanomaterials, e.g., carbon nanotubes or semiconductor nanowires, using an assembly of molecular precursors attached to a select substrate surface. By relying on various chemical interactions, the molecular precursors self-assemble on the selected surface. Exemplary surfaces on which to selectively grow carbon or semiconductor nanomaterials include device surfaces such as an electrode surface used in field-effect transistors, light emitting diodes, photovoltaic devices and sensors.
IBM inventors, Ali Afzali-Ardakani, Cherie R. Kagan and Laura L. Kosbar, earned a patent for this invention, which has the potential to greatly facilitate the incorporation of carbon nanotubes or semiconductor nanowires into real world electronics.

A new supercomputing-powered weather model may ready us for Exascale

In the U.S. alone, extreme weather caused some 297 deaths and $53.5 billion in economic damage in 2016. Globally, natural disasters caused $175 billion in damage. It’s essential for governments, business and people to receive advance warning of wild weather in order to minimize its impact, yet today the information we get is limited. Current […]
