In addition, FIB techniques are often preferred to prepare transmission-electron microscope (TEM) specimens, which are frequently impossible to make by any other conventional methods. In this paper, various FIB microscopy applications in microstructural characterizations are discussed using examples from ...
FIB的应用Focused Ion Beam 聚焦离子束显微镜 (Focused Ion Beam, FIB) 聚焦离子束显微镜是运用镓 (Ga) 金属来做为离子源。因为镓的熔点为 29.76°C,且在此时的蒸气压为«10-13 Torr,所以很适合在真空下操作。在…

1. 原理:FIB技术通过将液态金属(通常是镓Ga)的离子源产生的离子束经过加速和聚焦后照射到样品表面,可以产生二次电子信号以取得电子图像。同时,使用较高电流的离子束可对表面原子进行物理溅射,从而完成微米或纳米级别的表面形貌加工。 2. 操作模式:FIB的主要工作模式包括成像、切割和沉积/增强刻蚀。在制样过程中,可以...
FIB离子源技术 我们今天使用的聚焦离子束(Focused ion beam,FIB)仪器的技术起源于外太空,更确切地说,是应用离子束推进航天器。在太空中,只有通过喷射物质(即所谓的reaction mass)才能产生推力。除了基于燃烧的化学推进器外,离子推进器已成为高精度运动的重要工具。
聚焦离子束技术(FocusedIon beam,FIB)是利用电透镜将离子束聚焦成非常小尺寸的离子束轰击材料表面,实现材料的剥离、沉积、注入、切割和改性。随着纳米科技的发展,纳米尺度制造业发展迅速,而纳米加工就是纳米制造业的核心部分,纳米加工的代表性方法就是聚焦离子束。近年来发展起来的聚焦离子束技术(FIB)利用高强度聚焦离子...
Focused ion beam scanning electron microscopy (FIB SEM) instruments for automated structural analysis, TEM sample preparation, and nanoprototyping.
beam then rasters to cover an area on the sample. With a different kind of source, an electron beam can be used for nondestructive imaging and characterization without sputtering the sample surface, much like scanning electron microscopy (SEM). The combination of SEM and FIB paves a path for...
10-17a reveals grain orientation contrast unlike secondary electron SEM imaging; also unlike TEM methods, thick specimens that require no sample preparation can be imaged by FIB microscopy. In Fig. 10-17b the SEM electron backscatter (EBSD) image (see Sections 9.4.5 and 10.3.2.2) demonstrates ...
