WebSEM vs TEM: Differences in operation. The two EM systems also differ in the way they are operated. SEMs usually use acceleration voltages up to 30 kV, while TEM users can set it in the range of 60–300 kV. The magnifications that TEMs offer are also much higher … WebJun 1, 2024 · Scanning transmission electron microscopy performed in a scanning electron microscope (STEM-in-SEM) is undergoing a striking resurgence.
