2D perovskite derivative has potential for scalable valleytronic devices
Rice University and Texas A&M University researchers have found that a 2D derivative of perovskite could make computers faster and more energy-efficient. Their material has the ability to enable the valleytronics phenomenon, which is known as a possible platform for advanced information processing and storage.
The lab of materials scientist Jun Lou of Rice's Brown School of Engineering synthesized a layered compound of cesium, bismuth and iodine that is able to store the valley states of electrons, but only in the structure's odd layers. These bits can be set with polarized light, and the even layers appear to protect the odd ones from the kind of field interference that bedevils other perovskites, according to the researchers.
