The Dhaka Times Desk Using 2D materials like graphene can speed up modern-day electronic and photonic devices. Recently researchers have given such information.
Using 2D materials could make devices smaller and more efficient, a new study suggests.
According to the Times of India, 2D or two-dimensional materials are a class of nanomaterials that are a few atoms thick. Electrons are able to move freely in the two-dimensional plane of this material. But in the third dimension, quantum mechanics governs their movement. Scientists believe that 2D materials such as graphene, transition metal dichalcogenides and black phosphorus could also lead to improvements in electronic and photonic devices. Scientists spoke of this possibility after looking at the properties of these materials.
Researchers from the University of Minnesota and Stanford University in the US examined the optical properties of dozens of 2D materials. The researchers analyzed how polaritons, a class of quasiparticles, are produced by electronic charge dipoles and multiple photons. Because of the analysis, they were able to establish a correlation between the speed of the tiny electron and photon light particles.
Tony Lowe, assistant professor of electrical and computer engineering at the University of Minnesota and the lead researcher of this study, said, 'The device needs to be relatively small. We also want to see devices that are fast and efficient.'
