quark-confinement mesoscopic gas sensors Explanation: There are lots of hits on Yahoo for "mesoscopic gas sensors" (see also the first reference). When you check the reference at http://www.xrefer.com/entry/486847 for "confinement" it refers you to "quark confinement". No hits for "quantum" or "quantic" + "confinement" together. Anyway, I hope this puts you on the right track. Reference: http://www-lasers.llnl.gov/ Reference: http://www.xrefer.com/entry/486847 |

mesoscopic quantum confinement gas sensors Explanation: McGraw Hill Zannichelli: mesoscopic [FIS] mesoscopico Pertaining to a size regime, intermediate between the microscopic and the macroscopic, that is characteristic of a region where a large number of particles can interact in a quantum-mechanically correlated fashion.

in favor of quantum confinement Explanation: Reference one for quantum confinement quantum confinement: Light emission from bulk (macroscopic) semiconductors such as LEDs results from exciting the semiconductor either electrically or by shining light on it, creating electron-hole pairs which, when they recombine, emit light. The energy, and therefore the wavelength, of the emitted light is governed by the composition of the semiconductor material. If, however, the physical size of the semiconductor is considerably reduced to be much smaller than the natural radius of the electron-hole pair (Bohr radius), additional energy is required to "confine" this excitation within the nanoscopic semiconductor structure leading to a shift in the emission to shorter wavelengths. Zanichelli McGraw Hill quark confinement [FIS PART] confinamento dei quark The phenomenon wherein quarks can never be removed from the hadrons they compose, even though the interactions between them are relatively weak. quark [FIS PART] quark One of the hypothetical basic particles, having charges whose magnitudes are one-third or two-thirds of the electron charge, from which many of the elementary particles may, in theory, be built up; for example, nucleons may be formed from three quarks and mesons from quark-antiquark combinations; no experimental evidence for the actual existence of free quarks has been found. Quark confinement is a phenomenon of particle physics whereas quantum is a phenomenon of solid-state physics. Reference: http://www.qdots.com/new/glossary.html |
