Think of all the things God can do with these gadgets He has at His disposal...such as electronics... which we are still learning about...we've only scratched the surface of His "mysterious" gadgets...
"A new method that precisely measures the mysterious behavior and magnetic properties of electrons flowing across the surface of quantum materials could open a path to next-generation
electronics.
Found at the heart of electronic devices, silicon-based semiconductors rely on the controlled electrical current responsible for powering electronics. These semiconductors can only access the electrons' charge for energy, but electrons do more than carry a charge. They also have intrinsic angular momentum known as spin, which is a feature of quantum materials that, while elusive, can be manipulated to enhance electronic devices.
A team of scientists at the Department of Energy's Oak Ridge National Laboratory have developed an innovative microscopy technique to detect the spin of electrons in topological insulators, a new kind of quantum material that could be used in applications such as spintronics and quantum computing.
"The spin current, namely the total angular momentum of moving electrons, is a behavior in topological insulators that could not be accounted for until a spin-sensitive method was developed," Li said.
A topological insulator carries electrical current along its surface, while deeper within the bulk material, it acts as an insulator. Electrons flowing across the material's surface exhibit uniform spin directions, unlike in a semiconductor where electrons spin in varying directions.
To detect and better understand this quirky particle behavior, the team needed a method sensitive to the spin of moving electrons. Their new microscopy approach was tested on a single crystal of Bi2Te2Se, a material containing bismuth, tellurium and selenium. It measured how much voltage was produced along the material's surface as the flow of electrons moved between specific points while sensing the voltage for each electron's spin.
The new method builds on a four-probe scanning tunneling microscope—an instrument that can pinpoint a material's atomic activity with four movable probing tips—by adding a component to observe the spin behavior of electrons on the material's surface. This approach not only includes spin sensitivity measurements. It also confines the current to a small area on the surface, which helps to keep electrons from escaping beneath the surface, providing high-resolution results." Phys.org
And though I have ...understand all mysteries, and all knowledge;...and have not love, I am nothing.
