Researchers have used new photo-ferroelectric materials to store information in a non-volatile form using light exposure.
We are accustomed to the fact that under the influence of sunlight, materials heat up. However, photons can also have less noticeable effects, for example, create pairs of free charge carriers in insulators, which is the basis of photocells..
By studying photosensitive ferroelectric materials, scientists from the Barcelona Institute of Materials Science have found that they can be used to create more advanced storage devices. The team found that, with the right design, their electrical resistance could be modulated by pulsed light. This means that they can switch between low and high resistance states simply by light exposure, and the data will be retained even after the power is turned off..
In fact, such materials combine the properties of an optoelectronic sensor and a memory device. They will consume less energy due to the absence of the need for current flow and regular rewriting of information.
Scientists have found a new way to store information using light
Recall that recently, scientists also successfully transferred the light stored in a quantum memory device for the first time..
