论文摘要
旋转的电气控制一直是固态物理领域的长期目标,因为可能提高信息处理效率。可以通过将旋转基质转移到原子量表来优化这种效率。我们通过采用电子自旋共振扫描隧道显微镜(ESR-STM)来介绍单分子中自旋共振转变的电控制。我们发现ESR信号的强偏置依赖性偏移大约是其线宽的十倍,这是由于电场引起的隧道连接中自旋系统的位移所致。这为超快控制耦合自旋系统的超快控制开辟了新的途径,甚至针对原子量表量子计算,并扩展了理解和优化散装材料中的自旋电气耦合。
Electric control of spins has been a longstanding goal in the field of solid state physics due to the potential for increased efficiency in information processing. This efficiency can be optimized by transferring spintronics to the atomic scale. We present electric control of spin resonance transitions in single molecules by employing electron spin resonance scanning tunneling microscopy (ESR-STM). We find strong bias voltage dependent shifts in the ESR signal of about ten times its linewidth, which is due to the electric field induced displacement of the spin system in the tunnel junction. This opens up new avenues for ultrafast control of coupled spin systems, even towards atomic scale quantum computing, and expands on understanding and optimizing spin electric coupling in bulk materials.
