Discussion Overview

The discussion revolves around the Scherrer formula as it pertains to X-ray reflectivity studies of thin films. Participants seek to understand the fundamental concepts and applications of the formula within the context of their research projects.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • A new user expresses a need for an explanation of the Scherrer formula for their summer project on X-ray reflectivity studies.
  • Some participants inquire about the user's current knowledge and resources, suggesting that sharing what they know could lead to more effective assistance.
  • Multiple references and resources are provided by participants to aid in understanding X-ray diffraction and the Scherrer formula.
  • One participant emphasizes the importance of formulating specific questions based on existing knowledge rather than seeking general help.
  • The user mentions having a guide, Dr. P.V. Satyam, but expresses frustration over their unavailability for assistance.

Areas of Agreement / Disagreement

Participants generally agree on the need for the user to clarify their understanding and formulate specific questions. However, there is no consensus on the best approach to learning about the Scherrer formula, as some suggest self-study while others emphasize the need for direct help.

Contextual Notes

The discussion highlights limitations in the user's current understanding and reliance on external resources, as well as the challenges of obtaining guidance from their supervisor.

Who May Find This Useful

Individuals interested in X-ray reflectivity studies, particularly those working with thin films or studying X-ray diffraction techniques.

hello! i m the new user to the physics forum. i m working in a summer project now. my project is on the x-ray reflectivity studies of thin films. i want an explanation on scherrer formula. will u please learn me that.
thanks.

What do you know so far? What learning resources have you used so far?
 
Till now I've studied the book "x-ray diffraction studies of crystals" by A.Guiner. Will u please tell me any other books for reference and please teach me the fundamental idea.
 
hello! is there anyone online!

hello malawi_glenn! thank u for ur suggestions. but can u give me some ideas regarding scherrer formula!
thanks.
 
Well I think you can read throgh the material, and search for more. Then you can come back here and tell us what you have learned, and also more specified questions. I gave you plenty of material I think. Look at the library for books on solid state and X-ray diffraction.

In these forums, questions like "help explain this to me" seldom gives results.(see berkema´s answer). It is much better to tell how what you know so far and your goals etc.

Do you not have a proffessor for this project?

thanks again. you i have a guide named Dr. P.V. Satyam. But he always remains busy in other works. so i have a lot of problems to face. Hence i need some help from the forum mentors.

But that does not sounds like a good supervisor..
And I think you can find the info you need on this formula in the references I gave you and the library. Ask what it is you do not understand and what you know so far instead of just shouting "help me".
