Sentences with phrase «trapping electrons in an atoms»

Not exact matches

«By applying an intensity of 100 trillion watts per cm2, we were able to go beyond the Death Valley threshold and trap the electron near its parent atom in a cycle of regular oscillations within the electric field of the laser,» Jean - Pierre Wolf says enthusiastically.

«We thus wanted to know if, after the electrons are freed from their atoms, it is still possible to trap them in the laser and force them to stay near the nucleus, as the hypothesis of Walter Henneberger suggests,» he adds.

Like many spintronics researchers, University of Sydney physicist Dane McCamey and his colleagues targeted electrons of phosphorus atoms trapped in silicon.

Instead of trying to measure the mass directly, the researchers bound a single electron to a bare carbon nucleus and placed the resulting atom in a uniform electromagnetic field called a Penning trap (created in an apparatus similar to the one pictured above).

In both bulk and porous silicon the hydrogen atoms combine with these electrons, with the result that they no longer act as traps — a process called passivation.

They took a common defect called a neutral oxygen vacancy — a place where an oxygen atom should appear in the lattice but instead two electrons are trapped.

The width of the nanotubes trapped the electrons in quantum wells, in which the energy of atoms and subatomic particles is «confined» to certain states, or subbands.
