aTransmission electron microscope (TEM) images were taken using a JEOL 2100 transmission electron microscope operating at an acceleration voltage of 200 kV. 传输电子显微镜 (TEM) 图象使用经营在200千伏加速度电压的JEOL 2100传输电子显微镜被采取了。[translate]...
Lorentz microscopy is the study of magnetic structure (magnetic induction B) in the transmission electron microscope (TEM) and has been used to confirm the structure of Bloch skyrmions in B20 and Fe/Pd ML materials2,21,22 and study chiral Néel walls in films with interfacial DMI23,24. In ...
PURPOSE:To be able to observe an electron beam image even when photographic dry plates are renewed by fixing an image pickup element to the valve member of a gate valve mechanism, and then observing the electron beam image focused on an electron lens system through an image display unit in ...
In a transmission electron microscope, an electron beam from an electron gun (1) is irradiated on a specimen (3) by an illuminating lens system (2) and a transmission image of the specimen is formed on a photographic film (11) by an image forming lens system (4). The transmission image...
1. An image acquisition method for use in a transmission electron microscope, said image acquisition method comprising the steps of: setting at least one of a spherical aberration coefficient and a chromatic aberration coefficient of an imaging system of the transmission electron microscope to suppress...
The possibility of implementing a Zernike phase plate in a transmission electron microscope is investigated both theoretically and experimentally. The phase-retarding plate in the form of thin film with a hole in the center is positioned in the back-focal plane of the objective lens. The experiment...

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,...
Atomically resolved images of monolayer organic crystals have only been obtained with scanning probe methods so far. On the one hand, they are usually prepared on surfaces of bulk materials, which are not accessible by (scanning) transmission electron microscopy. On the other hand, the critical el...
