The Nobel Prize in Physics in the year 2010 was awarded for the graphene discovery. Graphene, which is a single layer of carbon atoms possesses properties that are considered as ideal for several applications. Among several researchers, graphene is considered as the hottest material for the last decade. In the last years, more than 30,000 research papers on the topic were published across the globe.
At present, two researchers from the Kansas, Professor Hui Zhao and the graduate student Samuel Lane, both from the Physics and Astronomy Department, have connected the graphene layer with the two other atomic layers (tungsten disulfide and molybdenum diselenide), thereby extending the lifetime of the excited electrons in the graphene by using several hundred times. These findings will be further published in the Nano Futures, which is a highly selective and newly launched journal.
For the purpose of optoelectronic and electronic applications, it has an excellent property of charge transport. As per the team of researchers, the electrons move in graphene at a speed of about 1/30 of the speed of the light, which is actually much faster than several other materials. This further states that it can be also used for solar cells that convert energy from sunlight into electricity. On the other hand, it has a major throwback, which is likely to hinder several applications, such as the ultrashort lifetime of excited electrons. These excited electrons are quite similar to students who stand up for their seats, especially after an energy drink.
