Energy distribution of backscattered electrons

Click For Summary

Discussion Overview

The discussion revolves around the concept of energy distribution of backscattered and transmitted electrons, focusing on how to calculate this distribution in various experimental setups. Participants seek to understand the nature of energy distribution and its dependence on specific conditions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • Some participants inquire about the meaning of energy distribution and how to calculate it for transmitted electrons.
  • It is noted that electrons will have varying energies, leading to an energy distribution, but the specifics depend on the experimental setup.
  • One participant emphasizes that there is no universal energy distribution for transmitted electrons, highlighting that different scenarios (e.g., tunneling vs. TEM) yield different distributions.
  • A participant mentions having calculated the transmission coefficient using Monte Carlo simulations and seeks the function for energy distribution of transmitted electrons.
  • Another participant suggests that the same simulations should provide the energy distribution relevant to the specific setup.
  • There is a clarification that the program calculating the transmission coefficient does not require prior knowledge of the energy behind the material, as it needs the energy distribution of incoming electrons instead.

Areas of Agreement / Disagreement

Participants express differing views on the existence of a universal energy distribution for transmitted electrons, with some asserting that it varies by setup. The discussion remains unresolved regarding the specific function for energy distribution.

Contextual Notes

Participants highlight the importance of specifying the experimental setup when discussing energy distributions, indicating that assumptions about the conditions can significantly affect the results.

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".

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.
