Abstract

Metallic nanostructures are applied in many fields, including photonics and plasmonics, due to their ability to absorb or emit light at frequencies which depend on their size and shape. It was recently shown that irradiation by a focused electron beam can promote the growth of nanostructures on metal surfaces and the height of these structures depends on the duration of the irradiation and the material of the surface. However, the effects on growth dynamics of numerous irradiation parameters, such as beam current or angle of incidence, have not yet been studied in detail. We explore the effects of focusing, angle of incidence, and current of the electron beam on the size and shape of the resulting structures on an Ag surface. In addition, we investigate how the nitrogen plasma cleaning procedure of a vacuum chamber can affect the growth of these structures. A beam current of around 40 pA resulted in the fastest structure growth rate. By increasing the beam diameter and angle of incidence the growth rate decreased; however, by raising the beam focus up to 5-6 μm above the surface the growth rate increased. Vacuum chamber cleaning reduced structure growth rate for a few hours. These findings can help to better control and optimise the growth of nanostructures on metal surfaces undergoing irradiation by a focused electron beam.

摘要

金属纳米结构因其能够在取决于其尺寸和形状的频率下吸收或发射光,而被应用于包括光子学和等离子体学在内的许多领域。最近有研究表明,聚焦电子束辐照可以促进金属表面纳米结构的生长,并且这些结构的高度取决于辐照持续时间和表面材料。然而,众多辐照参数,如束流或入射角,对生长动力学的影响尚未得到详细研究。我们探究了聚焦、入射角和电子束电流对银表面生成结构的尺寸和形状的影响。此外,我们还研究了真空腔室的氮等离子体清洗程序如何影响这些结构的生长。约40 pA的束流导致结构生长速率最快。通过增加束直径和入射角,生长速率降低;然而,将束焦点提高到表面上方5 - 6μm时,生长速率增加。真空腔室清洗在数小时内降低了结构生长速率。这些发现有助于更好地控制和优化在聚焦电子束辐照下金属表面纳米结构的生长。
