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.

0423908WANG这项研究的目标如下：1）研究新型颗粒状高通透性（高-M）材料，即co-Fe-HF-O具有M0MS 1.0 TESLA的饱和磁化和1000 MWCM的高电阻率，这将抑制当前损失损失和有效的效率的损失。 2）研究控制颗粒高-M材料中磁各向异性的基本机制，该机制在很大程度上被忽略但对电感器性能至关重要。 3）设计和制造集成的电感结构，这些结构将以200 MHz的频率真正释放高-M材料的功率。 4）通过博士学位论文研究，研究生研究经验（REU）和课堂教学教育研究生和本科生有关综合电感技术的教育。 拟议活动所产生的更广泛的影响包括：1）这项研究中的发现将使电力传递和无线通信设备以及许多其他微电子应用程序的小型化。 2）PI与英特尔和HGST建立了密切合作，以允许快速的技术转移到商业领域。 3）他与日本和荷兰的研究人员进行了合作，以产生国际影响。 4）斯坦福大学的拟议研究推力在过去两年中接待了三名本科研究人员（一名女性），并有望将来向更多的本科生宣讲。
