frameworksIn this section, we will review briefly and simply the depen-dence on external potential of the wave property of electronflux used on SEM and TEM technologies. For this reason, firstof all, it should be mentioned the influence of wave propertieson growing and resolution. The shortest distance between twopoints, which can be distinguished from each other, is calledresolution. For example, the average resolution for the humaneye is approximately 0.1–0.2 mm and the resolution in opticmicroscopes is much smaller than this value. In the generalcase, we can calculate the resolution of the microscope withthe following equation: ı = (0.61/ sin ˇ) (here – wavelength, – refraction index and ˇ – observation angle in zoom lens)
