Unlocking the Secrets of Eternal Data With Silicon Carbide

Team presents new path to long-term data storage based on atomic-scale defects.Show more

With the development of the internet, social media, and cloud computing, the amount of data created worldwide on a daily basis is skyrocketing. This calls for new technologies that could provide higher storage densities combined with secure long-term data archiving far beyond the capabilities of traditional data storage devices. An international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) now proposes a new concept of long-term data storage based on atomic-scale defects in silicon carbide, a semiconducting material. These defects are created by a focused ion beam, providing high spatial resolution, fast writing speed, and low energy for storing a single bit, as the team reports in the journal Advanced Functional Materials.
