Dijamanti: Od najtvrđeg materijala do superprovodljivosti

In a groundbreaking study, scientists have uncovered a way to alter the electronic properties of diamonds by manipulating their structure. Through an innovative technique called elastic strain engineering, researchers have successfully transformed diamonds from insulators to semiconductors, and even to superconducting materials. These findings pave the way for the widespread application of diamonds in fields such as solar panels, LED technology, high-voltage electronics, optical devices, and quantum sensors.

Using quantum mechanical calculations, analysis of mechanical deformations, and machine learning, a team of scientists from MIT achieved changes in the electronic properties of diamonds at the nano level. The idea was to rearrange the atoms within the crystal lattice without compromising the diamond structure itself.

The crucial property that determines a material’s conductivity is known as the “bandgap.” Diamond possesses a high bandgap value, which makes it an insulator. However, simulations demonstrated that it is possible to gradually modify the diamond’s bandgap, resulting in a wide range of electrical properties from an insulator to a superconducting material.

Professor Suresh Tao of City University of Hong Kong successfully bent a diamond nanoneedle by an astonishing 10% without causing any damage to its structure. This ability to manipulate the electronic properties of diamonds without altering their chemical composition or stability offers incredible flexibility in adapting their functions to different requirements.

This revolutionary technique can be applied to a broad range of semiconductors, introducing new possibilities in industries, medicine, and science. In the future, deformed diamonds could be used as solar panels capable of capturing the entire spectrum of light, eliminating the need for tandem devices. Additionally, this technology has the potential to be implemented as a wide-spectral photodetector.

While practical applications are yet to be realized, these discoveries open up new scientific and technological paths to the future, providing us with the ability to tailor diamonds to our needs.
