Subject: Review of your definition of bandstructure

Hi Andree,

I have gone through your definition of band structure and found the language concise and easy to understand with an appropriate level of detail. However there are some minor errors that needs to be corrected before being approved. Please see below for my specific comments.

Purpose: from my understanding, the purpose of the definition is clearly defined. The document stayed simple in terms of jargon which adheres to its intended audience.

Suggestions:

  • An area that could be more clear is the last sentence of the first paragraph when it is outlining what will be explained by this document. It is confusing to make the connection for different arrangement of electrons of different elements.
  • It was great that you went back to the basics explaining how elements are formed. This method gave the audience a common starting point to follow along with the concept. The diagram of the different materials (insulator, conductor, semi-conductor) and their Fermi level very helpful in visualizing and understanding the concept. The only feedback on that part would be maybe explaining what E means; I assumed E = energy level?
  • Be care with proper grammar usage while describing an object. For example while describing the situation, “clearer” should be used in place of “more clear”.
  • I would suggest including references for the figures that you included in your expanded definition. An in-text citation is needed along with citing the source of the figure in your reference list.
  • I would also suggest looking into the proper formatting of your reference list in the bottom of your document. One mistake I can spot is that your items should not be labelled with numbers.

Organization: I can see that the extended definition used the following expansion strategies: how does it work, what are its parts, what does it look like and how is it used or applied. They worked appropriately to understand a physical definition.

However, I would suggest to include headings for parenthetical definition, sentence definition and expanded definition. Furthermore, it may be useful to include subheadings in the expanded definition to break up long chunks of texts.

Overall I find this a useful definition explaining band structure to someone who has no exposure to solid state physic. I enjoyed the common starting point and limited use of jargon in this document. With some more editing this will be a great definition for band structure, Great work!

Please let me know if you have any questions,

Brian
