Facts | golden path to the devices of a few atoms thick




Researchers at the University of Kansas found that the introduction of additional components in the ultrafine materials can lead to a considerable improvement of thermal and electronic devices. Professor and chemist William Honsted and his group found that the introduction of gold atoms in the new material (thickness of only three atoms), molybdenum disulfide improves its electrical characteristics. Scientists are constantly thinking about how to make electronics smaller and more durable materials .

The study can serve for the improvement of transistors, photodetectors, sensors, and thermal conductive coatings, says researcher Vikas Berry. From a practical point of view, we can talk about the creation of ultra-fast and ultra-thin devices. And the speed and the minimum thickness of the devices are precisely those characteristics that are most interested users.

As the network research portal e! Science News, Vikas Berry’s laboratory studies the properties of a new generation of nano-materials, the thickness of only a few atoms. We are talking about graphene and boron-nitride layers. These materials are intended for use in electronics, composites with high mechanical properties and the latest biotechnological solutions. An example of the latest nanobiokompozitnogo material can serve as a material with butterfly wings . Vikas Berry speaks highly about the prospects of the finest materials:

Looking to the future, these structures with atomic thickness of the potential to revolutionize the electronics being used in the devices, the thickness of which will be only a few atoms.

In a recent study led them to Berry and research group focused on the transistors of molybdenum disulfide (MoS2), a material that has been allocated just two years ago. The material is a sheet having a thickness of only three atoms. It is more suitable for use in transistors than a graphene sheet, the thickness of which is only one carbon atom.

In the process of studying the structure of molybdenum disulfide, scientists realized that the sulfuric base material blends well with the noble metals, including those with the gold. When establishing a connection between the nanoscale gold and molybdenum disulfide, the compound obtained is excellent capacitor.

The results of this work can significantly improve the electronics of the future, making it the hyperfine. Scientists have found a way of cutting power consumption of those future ultrathin devices.

The plans scientists do more complex designs based on molybdenum disulfide. It’s about logic devices and sensors.
