Nanotubes of misfit-layered compounds for the development of nanoelectronics

Researchers from the Nanoscopy on Low Dimensional Materials (NLDM) group at the Instituto de Nanociencia y Materiales de Aragón (INMA), a joint centre between the CSIC and the University of Zaragoza, together with researchers from the Indian Institute of Technology (IIT) in Bombay (India), have managed to study and synthesize new materials in the form of nanotubes composed of two misfit lamellar structures with exceptional electrical properties for application in the field of nanoelectronics. The prestigious journal Materials Horizons (Royal Society of Chemistry) has selected this work for publication on its cover.

These nanomaterials, based on cobalt and strontium oxides, synthesized by the group of Dr. Leela S. Panchakarla (IIT Bombay, India), in a highly complex structure and chemical composition, which has a direct impact on their growth, formation and properties. Specifically, it has been possible to measure that these nanotubes have a higher electrical conductivity value than carbon nanotubes and the ampacity (maximum current that a conductor can carry) is higher than that of any inorganic oxide measured to date.

The work carried out by Dr. Simon Hettler (Marie Curie postdoctoral researcher at the University of Zaragoza) and Dr. Raúl Arenal (ARAID researcher at the University of Zaragoza and leader of the NLDM group) at the Laboratorio de Microscopías Avanzadas (LMA), has allowed us to know, in detail, the structure and atomic configuration of these nanomaterials, which is key to understanding not only their growth, but also their unique properties.

These new materials offer interesting prospects in the field of nanoelectronics, thanks to their great potential as interconnects in small electronic devices for high-power applications.
