摘要/Abstract

摘要：

二维(2D)材料的出现由于其良好的物理特性及对未来纳米电子设备的潜在应用,而引起了研究者的关注。Cr₂Ge₂Te₆(CGT)中的二维铁磁性已得到证明,然而对于二维CGT,一直缺乏电子输运特性与电场效应的研究。文中制备并鉴定了厚度仅为几nm的CGT铁磁薄片,这为由各种2D材料组成的范德华结构提供了前提条件,并进一步的展示了通过电场效应对2D CGT设备通道电阻进行的大幅度调制。实验结果证明了2D CGT栅极电压的可调性,同时也证明了铁磁2D材料CGT作为新型功能量子材料的潜力。

Abstract:

The emergence of two-dimensional (2D) materials had drawn great attention due to its fascinating physical properties and potential applications for future nanoelectronic devices. Two-dimensional ferromagnetism in Cr₂Ge₂Te₆ (CGT) had been demonstrated, however, for two-dimensional CGT, there had been a lack of research on electron transport properties and electric field effects. Therefore, CGT ferromagnetic sheeted with a thickness of only a few nanometers had been prepared and identified, which provided a very important piece for the van der Waals structure composed of various 2D materials. We further demonstrated the large modulation of the channel resistance of 2D CGT devices by the electric field effect. The experimental results illustrate the gate voltage tunability of 2D CGT and the potential of ferromagnetic 2D material CGT as a new functional quantum material for future use.

Key words: Two-dimensional material, nanoelectronics, ferromagnetic two-dimensional material, electric field effect, voltage adjustable
