Hard drives to get smaller
The hard drives in your computer could get even smaller as scientists have now discovered a novel technique to understand better the new properties that arise when two materials are put together. With a better understanding of how materials interface, scientists can tweak the properties of different materials more easily, and this opens doors to the development of better solar cells, novel superconductors and smaller hard drives.
Some of the most exciting condensed matter physics problems are found at the interfaces of dissimilar materials.
“If you put two materials together, you can create completely new properties,” said Andrivo Rusydi, an assistant professor at the National University of Singapore. “For instance, two non-conducting, non-magnetic insulators can become conducting and in some cases ferromagnetic and superconducting at their interface,” explained Rusydi.
