  • 研究摘要:

    本實驗室-自旋電子及新穎材料實驗室-的研究方向著重在從工程物理 (engineering physics) 的角度進行次世代記憶體及邏輯元件的開發,以及新穎材料 (novel/ermergent materials) 在自旋電子學 (spintronics) 中的應用。舉凡磁性材料裡的異常霍爾效應 (anomalous Hall effect)、磁性多層結構中的巨磁阻 (GMR) 及穿隧磁阻 (TMR) 現象、到過渡金屬及其他新穎材料中的自旋霍爾效應 (spin Hall effect) 等,都和當代凝態物理學及未來磁性記憶體產業的發展息息相關。目前我們和台積電 (tsmc)、工研院 (ITRI) 等 MRAM 團隊皆有合作,共同開發次世代自旋記憶體及邏輯元件。
