Energy distribution of backscattered electrons

  1. Oct 25, 2014 #1
    I would like to ask what does mean energy distribution ,and how can I calculate the energy distribution of transmitted electrons .
    Thanks

    The electrons will get different energies - some more, some less. This is called "energy distribution".
    What is the setup you consider?

    Hi,
    I want to know the function of enegy distribution of transmitted electrons.
    thanks mfb.

    Have you compared what you wrote with the title of the thread that you made? They don't match!

    Secondly, there is no such thing as a universal energy distribution of transmitted electrons. That is why mfb asked for the setup of the experiment! The transmitted electrons distribution for, say, tunneling electrons is different than the transmitted distribution in a TEM experiment! There isn't a generic, universal distribution!

    So don't be lazy, be explicit in what you want!

    BTW, this is not a HEP topic.

    Hi,

    I have calculated the transmission coefficient of electron with MONTE CARLO simulation,so I want to calculate the energy distribution and I didn't find the function of energy distribution of transmitted electrons.
    thanks

    The same simulations should give you the energy distribution for your specific setup.

    I have to insert the function of distribution in my program to get it that is why I search for the function of energy disribution of transmitted electrons.
    thanks for your help

    If your program calculates the transmission coefficient in a material, then you do not have to know the energy behind that material in advance. That does not make sense at all.

    Your program needs the energy distribution of the incoming electrons, but that is something completely different.
