APPLICATION NOTE II(영문)

16 WINDOW TO THE NANO WORLD with COXEM BF (Bright Field) images show a two-dimensional structure synchronized on the sample’s surface with signals transmitted, while a detector placed on the beam axis catching the electrons transmitted. This tool is useful especially when observing the information about the form and structure of ‘bulk samples.’ 1) Bright Field Mode DF (Dark Field) images are created without receiving the central beam and with a donut-shape detector installed in ‘spawn areas’ with sharp angles. This is useful when it is difficult to observe the structure in detail or when analyzing the structure of a defect. 2) Dark Field Mode You can use a STEM Holder that does not affect a light elements analysis for more accurate observation of light elements. 3) STEM with EDS Mode Asbestos(1) Large Intestine Neuron(1) Asbestos(2) Colorectal Cancer Neuron(2) Benefits Operation 12. ApplicationofScanningTransmissionElectronMicroscopy(STEM) COXEM’s STEM solution allows a large-area observation, which was limitedly possible with STEM- in-TEM, under a relatively low magnification. Analysis Solution for: - Bioecology Check the image with COXEM’s special sample holder. ‘Low Vacuum’ mode is useful in minimizing any damage to the sample. INTRODUCTION STEM is designed to project electron beams generated by an electron gun onto a sample and extract electrons transmitted to create an image from them. This system is generally used to observe cells, structures or Nano construction.
