USBling: store information in diamonds
Having problems with low memory storage? Do you have diamonds? Say no more! A group of physicist from the City College of New York have demonstrated the possibility of using diamond as memory storage. The researchers used a diamond containing defects known as nitrogen vacancy centers, whose crystals contained a number of holes where carbon atoms should be. The vacant holes usually held electrons, giving the features of a negative electrical charge. When a laser is shone in those negatively charge electrons it will be altered and become a neutral charge. This phenomena suggests that the diamonds could encode data. Similar to the use of lasers in DVD and similar technology, lasers will be used to read, write, erase and rewrite data. In principle, each bits of data may be stored in the diamond with a space of only a few nano meters wide. This space is very small compared to the features used data storage. Due to this, the researchers have no way of reading or writing data with such tiny features. Though, the researchers were able to encode data in 3-D as stacks of 2-D images.
