Science news articles about 'electron movement'

  • Superconductors get a boost from pressure

    ... wires because they don’t restrict electron movement, the essence of electricity. But to do this, the materials ... , changes occur in the copper-oxide planes, the electron spins behave differently, the vibrational energy ...
  • Gecko's lessons transfer well

    ... to as "Fermi-level engineering" for its ability to manipulate electron movement at the nanoscale. Combined, the techniques represent ... said could be scaled up easily, for embedding nanotube circuitry into electronic devices. His own goal is to develop ...
  • Electrons on the brink: Fractal patterns may be key to semiconductor magnetism

    ... , but also introduces disorder into the lattice structure that can hinder the electrons' movement and cause them to become "stuck ... that localization can occur for "quantum" particles, including electrons, when they encounter random obstacles, such as in doped semiconductors ...
  • Delayed time zero in photoemission

    ... short interval of time. But after excitation by light one of the electrons leaves the atom earlier than the other. Hence we were able ... poorly understood interactions have a fundamental influence on electron movements in tiniest dimensions, which determine the course ...
  • Graphene exhibits bizarre new behavior well suited to electronic devices

    ... , as in unstrained graphene. The energy levels are identical to those that an electron would occupy if it were moving in circles in a very ... , controlling their conductivity, optical or microwave properties. Control of electron movement is the most essential part of any ...
  • Material created at Purdue lets electrons 'dance' and form new state

    ... up and down and limiting their movement to front-to-back and side-to-side. "We are basically capturing the electrons within ... transport in semiconductors, takes the difficult measurements of the electrons' movement. The standard metric of semiconductor quality ...
  • Electronics takes on a new spin

    ... showed that light can be used to obtain information about the spin of electrons flowing over the material’s surface, and has even found a way to control these electron movements by varying the polarization of a light source ...
  • Opening the gate to robust quantum computing

    ... of the nucleus," said Dobrovitski. "We can separate out this particular single electron movement from thousands of others because it is synchronized with the motion of the nuclear magnetic moment." As a result, the electron's and nucleus' movements stay linked, while they are both ...
  • Solving electron transfer
