We investigate gate-regulated transition temperatures for electron hopping behaviours through discrete ionized dopant atoms in silicon junctionless nanowire *** demonstrate that the localization length of the wave function in the spatial distribution is able to be manipulated by the gate electric *** transition temperatures regulated as the function of the localization length and the density of states near the Fermi energy level allow us to understand the electron hopping behaviours under the influence of thermal activation energy and Coulomb interaction *** is useful for future quantum information processing by single dopant atoms in silicon.

A reverse micelle technique using non-ionic Birj 30 and n-heptane as surfactant and organic solvent, respectively, is introduced in this work to synthesize ferrous spin-crossover（SCO） nanoparticles of complex [Fe（NH2trz）3]（BF4）2·H2O（Fe L, NH2 trz = 4-amino-1,2,4-triazole）. By altering the type of solvent, the concentration of surfactant and co-surfactant, as well as the content of aqueous phase, the morphologies and sizes of nanoparticles of Fe L could be finely controlled. The formation of nanorods or spherical particles depended on the nature of solvent, while uniformity of the spherical and rod-like nanoparticles resulted from adjustment of co-surfactants. The size of the nanoparticles could be controlled between 4 and 550 nm by conducting the reactions in the aqueous phase with surfactant of different concentrations. The SCO critical temperatures of the spherical particles were higher than those of nanorods, and the widths of the SCO hysteresis loops decreased continuously with decreasing particle size. Interestingly, the complex particles became paramagnetic over the whole temperature range when the size was reduced to 3–5 nm.

transition metal complexes having d4-d7 electron counts in first-row are typically observed spin *** of the molecular bistability of spin-crossover,there is enormous interest for applications such as molecular switch,sensorsand digital memory.1 We systhesised a bis（α-iminopyridine）metal iodine complexes2（Scheme 1）.This complex consists of a neutralα-iminopyridine and a reducedπradical anion.A spin transition occurs at the temperature of ***-temperature single-crystal X-ray diffraction revealed that the S=1 to S=2 transition is associated with an increase in the Fe-N bond distances.
