Plot the Bremsstrahlung emitted (intensity vs energy) from a copper target for (i) both 15 keV and 30 keV electrons, (ii) for 15 keV electrons at both 10 and 50 mA current and (iii) for copper and molybdenum targets for 15 keV at 50 mA. Briefly discuss the impact of electron energy, electron current and target on the Bremsstrahlung generated.
An SEM offers a minimum magnification of 10x and a maximum magnification of 500,000x. For the lowest and highest magnification what would be the length scanned on the sample assuming a working distance of 5 mm and the final of image of 125 x125 mm displayed on a monitor.
The energy band formed by a series of energy levels having valence electrons is called as valence band. At 0 K, the electrons fulfill the energy levels in valence band initialising
Electron distribution: The atoms of a solid have electrons rotating in orbits around the positive nucleus. This is true of gases and liquids as well. These orbiting electrons
