Diamonds have the potential to conduct electricity
Today’s Video of the Day from NTU Singapore reveals that diamonds could potentially be manipulated to conduct electricity like metals.
The team used computer simulations to demonstrate that mechanical strain can be applied to nanoscale diamond needles to reverse their geometry and electrical properties. According to the researchers, this would give them a metal-like conductivity at room temperature and pressure.
“The ability to engineer and design electrical conductivity in diamond without changing its chemical composition and stability offers unprecedented flexibility to custom-design its functions,” said study co-author Professor Subra Suresh.
“The methods demonstrated in this work could be applied to a broad range of other semi-conductor materials of technological interest in mechanical, microelectronics, biomedical, energy and photonics applications, through strain engineering.”
