研究了单分散爆轰纳米金刚石（DND）的电性能；已确定电阻率约为 10(12) Omega/sq，仅观察到一条重要的传导路径。 DND 颗粒的介电特性也很好，介电损耗角正切值在 0.05-0.5 范围内。这些综合观察结果表明，DND 在电学方面的表现与薄膜金刚石相似，并且 DND 的电学应用值得追求。由于简单的室温超声处理已用于沉积，因此可以涂覆各种三维基材材料。单分散 DND 的电气用途的一个限制，至少在此处使用的未经处理的溶液形式沉积中，是在 400 摄氏度以上的温度下类金刚石特性的灾难性损失。 (C) 2010 美国物理研究所。 [号码：10.1063/1.3446966]
The electrical properties of monodispersed detonation nanodiamonds (DNDs) have been studied; a resistivity of the order of 10(12) Omega/sq has been determined, with only one significant conduction pathway being observed. The dielectric character of the DND particles is also good, with dielectric loss tangent values in the range 0.05-0.5 being recorded. These combined observations suggest DNDs behave in electrical terms similar to thin film diamond, and that electrical applications for DNDs are worthy of pursuit. Since a simple room temperature sonication process has been used for their deposition, coating a wide-range of three-dimensional substrate materials will be possible. A limitation on the electrical use the monodispersed DNDs, at least in the untreated, as-deposited from solution form used here, is the catastrophic loss of diamond-like character at temperatures above 400 degrees C.
