Debabrata Nandi,Kaushik Gupta,Arup Kumar Ghosh,Amitabha De,Sangam Banerjee,Uday Chand Ghoshse of the electron optics of a SEM is to produce a small electron probe at the specimen by demagnifying the smallest virtual cross-section of the electron beam near the cathode. For the practical operation of a SEM, it must be possible to vary the electron-probe size, aperture and current; these can

The calibration procedure typically involves measuring a known material such as copper that provides characteristic X-ray peaks at low photon energy (e.g., Cu L.-M

High resolution imaging has been developed with the aid of an extensive range of field emission gun (FEG) microscopes. The magnification ranges of these instruments now overlap those of the transmission electron microscope. Low-voltage microscopy us

Therefore, bulk specimens can be examined in the SEM with a size limited only by considerations of accommodation in the specimen stage. For the examination of images of topography contrast from metal and ceram
