Article Synopsis
- The interactions between electrons and electromagnetic fields have led to significant advancements in technology, exemplified by photon-induced nearfield electron microscopy (PINEM), which allows high-resolution detection of electric fields in nanostructures.
- However, PINEM has limitations, particularly its reliance on strong electromagnetic fields that can make it unsuitable for sensitive samples and its lack of capability to resolve complex information.
- To overcome these challenges, researchers introduce an algorithmic approach utilizing free-electron Ramsey-type interferometry, significantly enhancing sensitivity and phase reconstruction for nearfield imaging, paving the way for applications in imaging delicate biological samples and imaging confined light in greater detail.
Article Synopsis
- Spatial modulation of electron beams is important for applications like nanolithography and imaging, but traditional methods lack flexibility and tunability.
- This study introduces a new technique using light-driven spatial modulation of electrons by manipulating surface plasmon polaritons (SPPs), allowing for dynamic control over electron beam shapes.
- The approach achieves tunable electron distributions with verified coherence and opens up possibilities for advanced applications such as aberration correction, nanofabrication, and material characterization at ultrafast timescales.
