查询词典 atomic diameter

The diameter of nano-particle is small and its surface energy is high. Atomic valence bond of particle surface is not saturation and surface atoms have extremely physical and chemical activity. So, nano-particle is apt to agglomerate to make difficult to bring its excellent properties to completely play and to modify polymer.

The I-V characteristics of the diodes with 100μm diameter indicated that as the densities of V-defects on GaN films increased from 4.1×105cm-2 to 1.03×107cm-2, the Schottky barrier height decreased from 1.44eV to 1.19eV and the reverse bias leakage current at -1V is increased sharply from 10-10A to 10-7A . Further studies on a single V-defect using conductive atomic force microscope demonstrated that the value of forward current biased at 8V at V-defect side-walls appears to be one order higher than that of plain region, indicating that the conductivity mainly occurred at the side-walls of V-defect.
