Direct Current Hopping Conductivity in One—Dimensional Nanometre Systems

A one-dimensional random nanocrystalline chain model is established.A dc electron-phonon-field conductance model of electron tunnelling transfer is set up,and a new dc conductance formula in one-dimensional nanometre systems is derived.By calculationg the dc conductivity,the relationship among the electric field,temperature and conductivity is analysed.and the effect of the crystalline grain size and the distrotion of interfacial atoms on the dc conductance is discussed.The result shows that the nanometre system appears the characteristic of negative differential dependence of resistance and temperature at low temperature.The dc conductivity of nanometre systems varies with the change of electric field and trends to rise as the crystalline grain size increases and to decrease as the distroted degree of interfacial atoms increases.

Influence of second sideband excitation on the dynamics of trapped ions in a cavity

We study the dynamics of a trapped ion placed at an antinode of the standing wave inside a high finesse cavity with consideration of the second sideband excitation between the ionic internal levels and the light field. We investigate the entanglement of the three subsystems embodying the ionic internal levels, the vibrational mode of the ion and the cavity field.
