0423908WangThe objective of this research are as follows: 1) Investigate novel granular high permeability (high-m) materials, namely Co-Fe-Hf-O with a saturation magnetization of m0Ms 1.0 Tesla and a high resistivity of 1000 mWcm, which will enable suppression of eddy current losses and efficient inductor designs. 2) Investigate fundamental mechanisms controlling the magnetic anisotropy in granular high-m materials, which is largely neglected but critical to inductor performance. 3) Design and fabricate integrated inductor structures which will truly unleash the power of high-m materials at a frequency of 200 MHz. 4) Educate graduate students and undergraduates about integrated inductor technology via doctoral thesis research, research experience for under graduate (REU), and classroom teaching. The broader impacts resulting from the proposed activity include: 1) The discovery made in this research would enable miniaturization of power delivery and wireless communication devices, and many other microelectronics applications. 2) The PI has established close collaborations with Intel and HGST to allow a speedy technology transfer to the commercial sector. 3) He has collaborations with researchers in Japan and the Netherlands to make an international impact. 4) The proposed research thrust at Stanford has hosted three undergraduate researchers (one female) in the past two years and can be expected to outreach to more undergraduate students in the future.

本研究的目标如下：1)研究新型颗粒状高磁导率材料，即饱和磁化强度为m0ms 1.0特斯拉、高电阻率为1000 mW cm的Co-Fe-Hf-O，这将使涡流损耗的抑制和高效电感的设计成为可能。2)研究了颗粒高m材料中控制磁各向异性的基本机制，它在很大程度上被忽视了，但对电感性能至关重要。3)设计和制造集成电感结构，在200 MHz的频率下真正释放高m材料的能量。4)通过博士论文研究、本科生研究经验和课堂教学，对研究生和本科生进行集成电感技术教育。拟议活动产生的更广泛的影响包括：1)这项研究的发现将使电力输送和无线通信设备以及许多其他微电子应用得以微型化。2)PPI与Intel和HGST建立了密切的合作关系，使技术能够迅速转移到商业部门。3)他与日本和荷兰的研究人员合作，产生国际影响。4)斯坦福大学拟议的研究重点在过去两年中接待了三名本科生研究人员(一名女性)，预计未来将扩大到更多本科生。
