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.

实验结果发现，随著V型缺陷密度由4.1×105cm-2增加至1.03×107cm-2，在氮化镓表面蒸镀镍金属所制成直径为100μm的萧基元件之所属能障从1.44eV下降至1.19eV，而且在-1V的操作下反向偏压漏电流从10-10A急遽的攀升至10-7A；为了了解V型缺陷对厘米尺寸n-GaN萧基元件电流传导机制之影响，我们进一步的利用导电原子力显微镜(Conductive Atomic Force Microscopy， C-AFM)，特别针对单一个V型缺陷进行微观电性之量测。
