Research finds drastic changes in thermal conductivity of diamonds under stress

Researchers from the University of Texas at Austin have discovered that the thermal conductivity of diamonds can be significantly altered by applying mechanical strain. Using supercomputer simulations, they found that by flexing diamond, its ability to conduct heat can be increased or decreased by over 90%. This breakthrough, published in the Proceedings of the National Academy of Sciences, opens up new possibilities for the use of diamonds in microelectronics and optoelectronics. The study utilized advanced computational models and machine learning to map the effects of strain on diamond’s phonon properties.
