## Description

- description: "<100> oriented single-crystalline ZrC nanoneedles were successfully
    fabricated using a dual-beam FIB-SEM system. Atomic characterization of the pristine
    ZrC crystal confirmed the consistency and uniformity of nanoneedles’ crystallographic
    orientation, ensuring tip stability and precision. Nanoneedles with 10-100 nm
    tip radii were evaluated as field emitters, yielding field enhancement factors
    of 1.78×10⁷ to 4.85×10⁶ m⁻¹ and tip emission areas of 0.93-97.3 nm². This work
    underscores the importance of geometric optimization in improving field emission
    performance and demonstrates a scalable and efficient method for developing high-performance
    electron sources for advanced electron-beam applications."
