论文摘要
我们使用单周期Terahertz（THZ）瞬变和静态偏置电压作为外部控制参数，对金属纳米杆菌的光电链球链球进行了全面的实验和数值研究。分析偏置电压依赖性条纹频谱图，我们探索了由叠加静态场控制的THZ诱导的光电能量光谱的重塑。使用数值模拟来确定场贡献的局部场强和空间衰减长度，证明电子轨迹控制以及在具有动态和静态成分的密闭场中对相空间分布的操纵。
We present a comprehensive experimental and numerical study of photoelectron streaking at metallic nanotips using single-cycle Terahertz (THz) transients and a static bias voltage as an external control parameter. Analyzing bias voltage dependent streaking spectrograms, we explore the THz-induced reshaping of photoelectron energy spectra, governed by the superimposed static field. Numerical simulations are employed to determine the local field strengths and spatial decay lengths of the field contributions, demonstrating electron trajectory control and the manipulation of the phase space distributions in confined fields with both dynamic and static components.
