Abstract EN
In this experimental work, a cold electron emitter of the type MIM (Metal-insulator-Metal) was fabricated.
In this study, aluminum, insulating aluminum oxide and platinum were used.
Using an aluminum rod and then oxidizing the aluminum layer to form a thin layer of insulating aluminum oxide whose thickness is measured in nanometers.
And then evaporating a thin layer of platinum over the insulator layer, which is a layer also measured in nanometers.
This emitter needs to work under the influence of very low pressure, or in a vacuum.
And the emission of electrons in this case is under the influence of the electric field and a very high voltage difference, which goes up to 1000 volts and more, this voltage is suitable for operating an X-ray tube.
It is a physical phenomenon described using the famous FowlerNordheim equation that gives the relationship between current density J and electric field E.
It was clearly shown that the resulting current is subject to Fowler-Nordheim equation.
This is an electronic emitter that is used as a cold cathode in X-ray production equipment , which reduces the temperature of the X-ray tube by 1000 C0.
