Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is
In SEM, an electron beam with acceleration voltages of up to 30 kV is focused on the specimen (Inkson, 2016). The interactions between the electron beam and the specimen emit signals from the
Scanning electron microscopy (SEM) is an important electron microscopy technique that is capable of achieving a detailed visual image of a particle with high-quality and spatial resolution.

Unlike the Transmission Electron Microscope which uses transmitted electrons, the scanning electron Microscope uses emitted electrons. The
An SEM is a type of electron microscope that uses an electron beam to scan the sample. The electrons that are backscattered, as well as the ones that are knocked of the near-surface region of the object,
Fourier transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gaseous material.
The Scanning Electron Microscope (SEM) is used for observation of specimen surfaces. When the specimen is irradiated with a fine electron beam (called an
