#Existence of two-dimensional nanomaterial silicene questioned Sometimes scientific findings can shake the foundations of what was held once to be true causing us to step back

A recent study at the U s. Department of energy's Argonne National Laboratory has called into question the existence of silicene thought to be one of the world's newest and hottest two-dimensional nanomaterials.

Silicene was proposed as a two-dimensional sheet of silicon atoms that can be created experimentally by super-heating silicon

Both silicene and silicon should react immediately with oxygen but they react slightly differently. In the case of silicon oxygen breaks some of the silicon bonds of the first one

Because it consists of only one layer of silicon atoms silicene must be handled in a vacuum.

which has been mistaken as two-dimensional silicene. Some of the bulk silicon platelets were more than one layer thick said Argonne scientist Nathan Guisinger of Argonne's Center for Nanoscale Materials.

Each new series of experiments presented a new set of clues that this was in fact not silicene.

We found out that what previous researchers identified as silicene is really just a combination of the silicon

Their sample did not exhibit characteristic vibrations of silicene but it did match those of silicon.

#Discovery is key to metal wear in sliding parts (w/Video) Researchers have discovered a previously unknown mechanism for wear in metals:

#One-atom-thin silicon transistors hold promise for super-fast computing Researchers at The University of Texas at Austin Cockrell School of engineering have created the first transistors made of silicene, the world thinnest silicon material.

silicene has outstanding electrical properties but has until now proved difficult to produce and work with.

solved one of the major challenges surrounding silicene by demonstrating that it can be made into transistors emiconductor devices used to amplify and switch electronic signals and electrical power.

Until a few years ago, human-made silicene was a purely theoretical material. Looking at carbon-based graphene

Akinwande, who also works on graphene transistors, sees value in silicene relationship to silicon, which chipmakers already know how to work with. part from introducing a new player in the playground of 2-D materials, silicene,

with its close chemical affinity to silicon, suggests an opportunity in the road map of the semiconductor industry,

Akinwande said. he major breakthrough here is the efficient low-temperature manufacturing and fabrication of silicene devices for the first time.

silicene has proved extremely difficult to create and work with because of its complexity and instability when exposed to air.

to develop a new method for fabricating the silicene that reduces its exposure to air.

They then formed a silicene sheet on a thin layer of silver and added a nanometer-thick layer of alumina on top.

They were then able to gently scrape some of the silver to leave behind two islands of metal as electrodes, with a strip of silicene between them.

and methods for creating silicene, which may lead to low energy, high-speed digital computer chips p

#Graphene displays clear prospects for flexible electronics Published in the scientific journal Nature Materials, University of Manchester and University of Sheffield researchers show that new 2d esigner materialscan be produced to create flexible, see-through and more efficient electronic devices.

#Single Atom Building blocks For Future Electronics The material is called a silicene, a layer of silicon single atoms arranged in a honeycomb pattern that was fabricated first by researchers at UOW Institute for Superconducting and Electronic Materials (ISEM) and their partners in Europe and China.

and Dr Yi Du have published breakthrough research into a new material call silicene. Silicene great promise is related to how electrons can streak across it at incredible speed

close to the speed of light. Propelling the electrons in silicene requires minimal energy input, which means reducing power and cooling requirements for electronic devices. f silicene could be used to build electronic devices,

it could enable the semiconductor industry to achieve the ultimate in miniaturization, Dr Yi Du,

a research fellow at the ISEM, said. The difficulty for researchers, according to Dr Du, is that up until a couple of years ago,

was the first research group in Australia to make silicene and recently, using state-of-the-art equipment,

and modifying silicene so it can be integrated it into ultra-small renewable energy devices, such as solar cells,

data storage hardware and advancing quantum computing. uow195685 o one in the scientific community believed silicene paper could be made

and place them one at a time on a plate to form the silicene paper. he process is like laying bricks,

and high-quality silicene layers that are large enough for integrated circuits, Dr Du said. here is also work to be done in developing ways to peel

and transfer the silicene layers from the base it has been assembled on, as well as embed electrodes in it. s
