X-ray absorption by semiconductors

Click For Summary

Discussion Overview

The discussion revolves around the absorption of X-ray spectra by semiconductor materials such as Silicon, GaAs, and CdTe. Participants are exploring the interactions between X-rays and these materials, particularly in the context of using the XOP software for simulations related to X-ray absorption spectroscopy (XAS).

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant seeks clarification on the interactions and results of X-ray absorption by Silicon, GaAs, and CdTe, questioning what happens to the X-ray spectrum and whether any atomic reactions occur.
  • Another participant suggests that the XOP software is primarily designed for synchrotron science and may not be suitable for analyzing absorption phenomena in semiconductors.
  • Some participants argue that the software has options for filtering with different materials, but its primary function is to analyze beam characteristics rather than X-ray absorption.
  • There is a suggestion that other software options like Athena, Iffifit, and Xcurve may be more appropriate for analyzing X-ray absorption spectra.
  • One participant emphasizes the need for clarity on the specific goals of the inquiry rather than focusing on the software itself.
  • Repeated requests for explanations about the absorption process itself, rather than software-related assistance, highlight a desire for conceptual understanding.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the suitability of the XOP software for the intended analysis, with some asserting it is not appropriate while others suggest it may have relevant features. The discussion remains unresolved regarding the specific mechanisms of X-ray absorption in the mentioned semiconductors.

Contextual Notes

Participants express uncertainty about the capabilities of the XOP software and its relevance to their project, indicating a potential lack of clarity in the software's intended use versus the participants' needs for understanding X-ray absorption phenomena.

Hi,
i am doing a project course in masters. i need help regarding on X-ray Spectrum absorption by semiconductors. I am doing the simulations in XOP(X-ray oriented programs) software which is freeware at http://www.esrf.eu/UsersAndScience/Experiments/TBS/SciSoft/xop2.3 . So, my doubt is when the spectrum of X-rays are absorbed by Silicon, GaAs and CaTe(candium telliride), i read the output wave form from the above software but i don't know reason for why we going for this type interactions and what is the result of this actions. what happened to X-ray sprectrum after. weather any reactions takes plave between the atoms of that materials. if so, give the explanation abt this.

thanks in advance...

Hi,
I guess that software is mainly designed for synchrotron science (to me it looks like a software for controlling beam quality). Not for analyzing and absorption phenomenon for semiconductor materials..
 
no there are ineer option to check the sprectrum like filtering with different materials and also some other options not related to my project
 
It is X-ray optics software and may not suit you.
It is for analysing the undulator or wiggler spectrum, etc..
And in ESRF generally semiconductors like silicon crystals are used for monochromatization of the beam (In Advanced photon source and DLS diamond crystals are used). So there may be some option in the software to try different semiconductors to check the resolution after monochromatization.. So absolutely not useful for you.
 
this is the project from last three years in my univ and all are doing in that software and also i have got old report from students but i can't copy the things from those data. so i need to know the things. if u downloaded the software means go to optics->mirrors and filters->in that choose last option -> it will open new window and ask for *set parameters*-> in that chose only one filter -> give material name(in my casr Si, GaAs, CdTe) what you want to filter and cilck show to visuailize the plot...now i wnat to know about the reponse what you will get after all the process as i said. what makes the difference between these filters and how should i explaine the result...please clear me out..
 
Hi,
I guess you want to try for your specific material.. May be the new version might have changed. So better ask you friends..
cheers
 
First you should be clear WHAT you want rather than trying to learn the code/software. If you want to analyze the X-ray absorption spectra, then clearly this is not the software for you. It seems more inclined towards the analysis of the beam itself and its characteristics. Though (from the screencasts) it seems that it CAN be used for the analysis of XAS, but it is not the best of the available options. If you could clearly mention WHAT you want, then someone can help you better.
 
For XAS,
Athena, Iffifit, Xcurve can be useful.

I don't want any suggestions about software or any thing related to software. i need to know abouy how the X-rays absorption will happen if you used semiconductors like Silicon, GaAs and CdTe as a filter. I need some explanation about these concepts.

Hi,
From your post (please see above) it seems that you are asking for some idea regarding the usage of the software XOP. Therefore, abhi2005singh and myself trying to give you some hints.
