Electron Energy Loss Spectroscopy (EELS):An advanced technique where energy losses experienced by electrons interacting with the sample are measured, providing detailed information on chemical composition, bonding, and electronic structure. EELS is particularly effective for analyzing light elements and unders...
Transmission Electron Microscope HF5000 Hitachi's unique 200 kV aberration-corrected TEM/STEM: the perfect harmony of imaging resolution and analytical performance 0.078 nm spatial resolution in STEM is achieved together with high specimen-tilt capability and large solid angle EDX detector(s), all in...
scanning transmission electron microscope microanalysismaterialsThe dedicated stem equipped with field emission electron source, affords opportunities for the acquisition of microchemical and microstructural data on a scale approaching the nanometer level. In this presentation, a number of applications of ...
As a high-end scientific instrument, a transmission electron microscope (referred to as a transmission electron microscope) can easily observe the internal structure of a sample, which is at least tens of thousands of times smaller than the smallest structure that can be observed with an optical ...
The size of viruses is with a few exceptions (the mimiviruses, poxviruses and some iridoviruses) below the resolution of the optical microscope. The 1000 times higher resolution of the transmission electron microscope (TEM), compared with the light microscope, allows direct observation of small ...

especially the semiconductor industry which relies on scanning electron microscopes (SEMs) for “in fab” defect analysis and metrology. However, as fabricated devices have grown in complexity, requiring higher resolution data on 3D structures, the use of transmission electron microscope (TEM) systems...
The two major types of TEM instruments are the conventional TEM (also referred to simply as TEM) and the STEM (scanning transmission electron microscope). Other variations of TEMs include the AC-S/TEM (where AC stands for “aberration corrected”) and the E-S/TEM (where E stands for “...
答案是 it depends。一般来说,TEM的分辨率要在1到2个纳米,STEM更高,但是STEM得成像技术类似于SEM,但用的不是二次电子。我们知道,宏观尺度上成像靠的是可见光,可见光在此的表现的是电磁波,波长范围在390nm到720nm,远比任何宏观尺度小得多,根据瑞丽准则(Rayleigh criterion),可见光的分辨率极限大概在200nm左右,...
