How to create an electron micro-scale structure

article Electron micro-scattering is a fundamental component of the electron, a tiny particle which can be used to capture light from atoms.

But to produce a micro-chip with the ability to carry out this work, scientists have had to make a lot of changes to their design. 

The most important change is to have a structure with a lot more surface area, a key component for micro-electronics. 

Scientists have been working on this problem for decades, and in fact it is not the first time they have made significant improvements. 

In a 2009 paper published in Nature, researchers from the University of Cambridge and the University at Wroclaw described how they had developed a structure which would enable them to capture and trap a single electron in an atomic structure, in a manner similar to how they could create a microchip. 

They have since refined their design to produce the most efficient system that would allow them to conduct this type of electron capture. 

But in the new study, they have created a new microchip that has a surface area of almost 300 nanometres, much smaller than the previous work, and which can conduct a single, high-speed electron beam.

The new chip could be used for a range of applications, including electronics, optoelectronics, optical communications and sensors, says lead researcher, Professor David Storch.

“These new microchips will be important for applications like quantum computing and photonics, where it is possible to do a lot faster and better things,” he said.

“The challenge with these microchipped chips is that they are just too small to make them very efficient for high-performance quantum computing, so that’s where we’re going.”

Electron microscattering can be achieved by creating a “polarisation” layer, which absorbs light and stores the energy as a magnetic field.

By doing this, electrons in the polarisation layer will be attracted to the light source, while the light will pass through the polarised layer, creating a photoelectric effect. 

Professor StorCh explained how it works in a paper he presented at the USENIX Photonics Conference in October, and explains that this process can be performed on a single molecule of silicon. 

“One of the things we’ve found in this research is that the electrons have to be polarised in order to carry electrons through the surface of a molecule,” he explained.

“When they have to do that, the electrons are attracted to a polarised surface.”

This is how a polarisation process works.

“The researchers’ new micro-chips are smaller than silicon chips, but are not a nanometer.”

They’re about 1,000 nanometre across,” he says.”

What’s exciting is that we’ve achieved a surface of about a million nanomettes, so we can use it to perform a very efficient electron-capture method, and a very high-energy-density device.” 

Professor David Storgch and his colleagues are currently working on another new design, but for now, this new micro chip is a significant step forward.
