Power amplifiers for energy-efficient 5G
The wireless data transmission via mobile communication is reliable and affordable. However, data volume per user is rising exponentially. Causes are not only the continuously growing number of smartphones, but also trends as V2V or M2M communication – cars and machines need to communicate in high speed with each other. From 2020 the 5G mobile standard is aiming to transmit data rapidly and energy-efficiently.
Nanocrystals grown in nanowires
An international team using resources at the Center for Functional Nanomaterials tailored extremely small wires that carry light and electrons. They devised an approach that lets them tailor the wires through exquisite control over the structures at the nanoscale. New structures could open up a potential path to a wide range of smaller, lighter, or more efficient devices.
Boron boosts graphene's sensitivity to noxious gases
Detecting noxious gases, such as those released from power plants and other sources that can harm the environment, is something graphene does well, but it could be even better. Researchers discovered a way to significantly improve its performance by peppering high-quality graphene sheets with boron impurities. Compared to pristine graphene, these modified sheets, a.k.a. boron-doped graphene, were 27 times more sensitive at detecting nitrogen diox...
Making freestanding single-atom silicon layer
Much like an overcooked dinner, the next so-called wonder material for next-gen electronics has been 'stuck to the pan' until researchers at the UOW's Institute for Superconducting and Electronic Materials (ISEM) came up with a breakthrough solution.The material is silicene, the thinnest possible form of silicon, comprised of a two-dimensional layer of silicon crystals.
Thin-film transistors developed for wearable display
With the advent of the IoT era, strong demand has grown for wearable and transparent displays that can be applied to various fields such as augmented reality (AR) and skin-like thin flexible devices. However, previous flexible transparent displays have posed real challenges to overcome, which are, among others, poor transparency and low electrical performance.
2D materials could be fine-tuned to the demands of industry
Extremely thin stacks of 2D materials, which could deliver applications fine-tuned to the demands of industry, are set to revolutionise the world in the same way that graphene will.Writing in Science, leading 2D materials researchers estimate that research on combining materials of just a few atomic layers in stacks called heterostructures is at the same stage that graphene was 10 years ago, and can expect the same rapid progress graphene has exp...
2D nanomaterials enables graphene electronics applications
Graphene has emerged as one of the most promising two-dimensional crystals, but the future of electronics may include two other nanomaterials, according to a study by researchers at the University of California, Riverside and the University of Georgia. In research published in the journal Nature Nanotechnology, the researchers described the integration of three very different 2D materials to yield a simple, compact, and fast VCO device.
Highly conductive materials for more efficient electronics
Engineers from the University of Utah and the University of Minnesota have discovered that interfacing two particular oxide-based materials makes them highly conductive, a boon for future electronics that could result in much more power-efficient laptops, electric cars and home appliances that also don't need cumbersome power supplies.Their findings were published in the scientific journal, APL Materials, from the American Institute of Physics.
Understanding the properties of the latest solar cells
As climate change garners more attention around the world, scientists at the University of Virginia and Cornell University have made critical advances in understanding the physical properties of an emerging class of solar cells that have the potential to dramatically lower the cost of solar energy.Solar cells remain a focal point of scientific investigation because the sun offers the most abundant source of energy on earth.
Ultra-flat circuits could have unique properties
The old rules don't necessarily apply when building electronic components out of two-dimensional materials, according to scientists at Rice University.The Rice lab of theoretical physicist Boris Yakobson analysed hybrids that put 2D materials like graphene and boron nitride side by side to see what happens at the border. They found that the electronic characteristics of such "co-planar" hybrids differ from bulkier components.
