Sentences with phrase «phosphorus atom in»

The single - atom transistor is made by carving a slot in a hydrogen - coated silicon wafer with a tunneling electron microscope and depositing a single phosphorus atom in the hole.

The experiment is a much more practical version of a study Boehme and colleagues published in Science in 2010, when they were able to read nuclear spins from phosphorus atoms in a conventional silicon semiconductor.

Not exact matches

Silicon - 28 is not magnetic so the atoms had almost no effect on the magnetic moment, or nuclear spin, of the phosphorus, meaning that these atoms behaved as though they were in a vacuum.

And the progress goes on: Late last year, researchers in Finland and Australia built an experimental transistor out of a single atom of phosphorus.

And in this case, the scientists found that the phosphorus had a little patch of negative charge, just enough to hook up with the hydrogen atom.

The group's setup swaps out a silicon atom for a phosphorus one in a silicon wafer, introducing an extra «donor» electron that can be manipulated and measured.

Phosphorus - doped silicon is a promising medium for spintronics because each phosphorus atom «donates» an extra electron that orbits rather freely and hence is open to manipulation in the silicoPhosphorus - doped silicon is a promising medium for spintronics because each phosphorus atom «donates» an extra electron that orbits rather freely and hence is open to manipulation in the silicophosphorus atom «donates» an extra electron that orbits rather freely and hence is open to manipulation in the silicon crystal.

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

Chemists at the Technische Universität München (TUM) have now developed a semiconducting material in which individual phosphorus atoms are replaced by arsenic.

A lone atom of phosphorus embedded in a sheet of silicon has been made to act as a transistor.

The spin of the electrons in isolated phosphorus atoms could serve as qubits, the quantum equivalent of the bits in today's computers.

The researchers were able to peer inside elements like phosphorus and sulfur with incredibly high «time resolution,» exciting the electrons in the deepest part of those atoms.

«Our decade - long research program had already established the most long - lived quantum bit in the solid state, by encoding quantum information in the spin of a single phosphorus atom inside a silicon chip, placed in a static magnetic field.»

In addition, gold clusters with the phenyl - containing ligand fragmented through a wide range of dissociation channels involving the loss of gold atoms as well as activation of the phosphorus - carbon bonds of the ligands.

Methods: Diphenylphosphine ligands, which consist of two phenyl (C6H5) substituted phosphorus centers separated by a carbon chain of variable length, produce gold clusters with extremely narrow distributions in size; that is, the synthesis route produces a large quantity of clusters with the same number of gold atoms as well as a small number of clusters with similar numbers of atoms.
