项目摘要
Award Title:Symmetry-protected spin dynamics in ferroelectric spin device (Proposal ID: 2031692)Non-technical Abstract:To boost the computing power of microelectronic systems, among many strategies such as device miniaturization, using non-charge-based logic operation and harnessing non-von Neumann architectures, computing with electron spin has been proposed as a promising solution. Spin devices such as spin field effect transistor are considered to have the potential to significantly advance computing performance and even transform current computing paradigms. In spin devices, control of electron spin – a computing process – is achieved by electric field-induced effective magnetic field in the hosting semiconductor. In most semiconductors, the magnetic field is multi-directional so coherent control of electron spin precession has been a challenge. In this project, the PI will address this issue by developing material/device systems that provide unidirectional magnetic field. In the proposed system, electric field stems from ferroelectric polarization and unidirectional magnetic field is a natural consequence of the unique symmetry of the proposed system. The nonvolatile electric field and the unidirectional magnetic field will make the proposed spin devices excel in spin control and power consumption. This award supports the fundamental research of understanding symmetry-spin dynamics relation in ferroelectric spin devices. The basic knowledge obtained from this project would help the realization of technologically practical spin field effect transistors. The results from this award will therefore benefit the U.S. economy by advancing technological progresses in the field of microelectronics. The award will also promote engineering education and research training of underrepresented groups. Technical Abstract:The research objective of this project is to understand the role of symmetry and the persistent spin helix on the spin dynamics in ferroelectric semiconductors with strong spin-orbit coupling for spintronic devices. While strong spin-orbit coupling enhances spin precession leading to short channel operation, it also simultaneously suppresses controllable spin transport. Such dilemma has been a major roadblock for realization of practical spintronic devices such as spin field effect transistors. In this project, by using semiconducting ferroelectric materials of selected symmetry with strong spin-orbit coupling, the PI expects to achieve symmetry-protected long-range coherent spin transport via persistent spin helix and switchable spin texture upon changing the ferroelectric polarization. To pursue these goals, the PI will grow high-quality single crystalline ferroelectric semiconductors carrying strong spin-orbit coupling, and fabricate ferroelectric spin valves and field effect transistors. The PI will investigate the spin-polarized band structure and persistent spin helix in the model materials. The PI will reveal the spin lifetime and spin diffusion length in ferroelectric spin valves and field effect transistors. The PI will also study the dynamics of ferroelectric domain structure and effect of ferroelectric domain orientation on persistent spin helix, spin dynamics, spin operation and diffusion. This proposed work will advance the fundamental knowledge needed in resolving the intrinsic dilemma issue between the precise manipulation and effective preservation of spin in spintronic systems with strong spin-orbit interaction.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
奖项名称:铁电自旋器件中的对称保护自旋动力学(提案编号:2031692)非技术摘要:为了提高微电子系统的计算能力,在器件小型化、使用基于非电荷的逻辑运算和利用非冯·诺依曼架构等众多策略中,电子自旋计算被认为是一种有前途的解决方案。自旋器件,如自旋场效应晶体管,被认为有潜力显着提高计算性能,甚至改变目前的计算模式。在自旋器件中,电子自旋的控制-一个计算过程-是通过托管半导体中的电场感应有效磁场来实现的。在大多数半导体中,磁场是多方向的,因此电子自旋进动的相干控制一直是一个挑战。在本项目中,PI将通过开发提供单向磁场的材料/器械系统来解决这一问题。在所提出的系统中,电场源于铁电极化和单向磁场是所提出的系统的独特对称性的自然结果。非易失性电场和单向磁场将使所提出的自旋器件在自旋控制和功耗方面表现优异。该奖项支持理解铁电自旋器件中自旋-自旋动力学关系的基础研究。从这个项目中获得的基本知识将有助于实现技术上实用的自旋场效应晶体管。因此,该奖项的成果将通过推动微电子领域的技术进步而使美国经济受益。该奖项还将促进工程教育和研究培训的代表性不足的群体。 技术摘要:本项目的研究目标是了解对称性和持续自旋螺旋对自旋电子器件中具有强自旋轨道耦合的铁电半导体自旋动力学的作用。虽然强自旋轨道耦合增强自旋进动导致短沟道操作,它也同时抑制可控自旋输运。这种困境已经成为实现诸如自旋场效应晶体管的实际自旋电子器件的主要障碍。在这个项目中,通过使用具有强自旋-轨道耦合的选择对称性的半导体铁电材料,PI期望通过改变铁电极化时的持久自旋螺旋和可切换的自旋织构来实现受保护的长程相干自旋输运。为了实现这些目标,PI将生长高质量的单晶铁电半导体,并制造铁电自旋阀和场效应晶体管。PI将研究模型材料中的自旋极化能带结构和持续自旋螺旋。PI将揭示铁电自旋阀和场效应晶体管的自旋寿命和自旋扩散长度。PI还将研究铁电畴结构的动力学和铁电畴取向对持续自旋螺旋、自旋动力学、自旋操作和扩散的影响。这项工作将推进解决自旋电子系统中自旋的精确操纵和有效保持之间的内在困境问题所需的基本知识,具有强自旋轨道相互作用。该奖项反映了NSF的法定使命,并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
