The new ultra-fast microscope for the quantum world, Component performance for future computers can now be recorded in HD quality, that is.
Researchers have now developed a microscope for a very fast process that occurs at the quantum scale. This microscope – something like an HD camera for the quantum world – allows precise tracking of the movement of electrons to one atom. the new ultra-fast microscope for the quantum world.
Therefore, it must provide useful information, for example when it comes to developing electronic components that are very fast and very small.
The processes in the quantum world are a challenge for even the most experienced physicists. For example, things that happen to computer components or smartphones that are getting stronger not only happen very quickly, but also in less and less space.
For example, when it comes to analyzing these processes and optimizing transistors, electron video will be very beneficial for physicists.
To achieve this, researchers need a high-speed camera that exposes each picture in this “electronic video” for only a few hundred seconds. ultra-fast microscope for the quantum world.
Atosecond is one millionth of a millionth of a second; During this time, light can only travel through the length of water molecules. For several years now, physicists have used fairly short laser pulses as an atosecond camera.
However, in the past, atosecond images only provided electron snapshots over a background that was basically blurred.
For this purpose, both physicists use ultra-fast laser pulses in conjunction with a scanning tunneling microscope. The latter reaches atomic-scale resolution by scanning the surface with peaks, which ideally consist of only one atom. Electronic tunnels between the top and the surface – that is, they cross the intervention room, even though they don’t actually have enough energy to do it.
Because the efficiency of this tunneling process depends very much on the distance the electrons must travel, the distance between the tip and the sample can be measured and each atom and molecule can be displayed on the surface.
But so far, scanning tunneling microscopes have not reached a resolution of time sufficient to track electrons.
By combining a tunneling scanning microscope with ultra-fast pulses, both methods can be easily used to compensate for each other’s shortcomings. The researchers fired very short pulses of light at the tip of the microscope – which are positioned with atomic precision to trigger the tunneling process.
As a result, this high-speed camera for the quantum world can now reach HD resolution.
With new technology, physicists can now measure up to one atom and with accuracy of several hundred atoseconds exactly where electrons are at a certain point in time.
This can be used, for example, in molecules where electrons are thrown by high-energy light pulses, which allows other negative charge carriers to rearrange and the molecules eventually react with other molecules.
Electrons are trapped in molecules on their natural spatial and temporal scales. It is therefore important to understand chemical reactivity and the conversion of light energy into charged particles such as electrons or ions.
In addition, this technology not only allows researchers to track the path of electrons through future processors and chips, but can also cause dramatic acceleration of charge carriers: ultrashort light pulses can be increased to one trillion hertz.
With this turbo amplifier of light waves, researchers can pave the way for electronic light waves that are millions of times faster than today’s computers.
Therefore, ultra-fast microscopes not only film processes in the quantum world, but also act as directors by interfering with this process.
