Abstract
We analyzed the high frequency dielectric relaxation mechanism in high-k composite materials using film substrates made of low loss organic resin filled with ferrolectric ceramics and with single wall carbon nanotubes (SWNT). The highest frequencey relaxation process dominates the overall loss characteristic. In the case of poymers modified with SWNTs, we observed that 2% of p-doped semi-conducting SWNTs increases the dielectric constant by 3 orders of magnitude, in apparent violation of the mixing-rule. The hybrid material appears to have preferential coupling within the dispersed phase. The experimental data and numberical simulation indicate that these materials can play a significant role as embedded passive devices with functional characteristic superior to that of discrete components.
