Graphene ribbon and Landau Energy Bands of Graphite

Click For Summary
SUMMARY

The discussion revolves around the challenges faced by a student at Ankara University in plotting energy levels of tight-binding electrons in graphene ribbons under a magnetic field for their thesis on Landau Energy Bands of Graphite. The student is struggling to extract data from a PDF article titled "The electronic properties of graphene" by A.H. Castro Neto and F. Guinea, published in January 2009. Participants in the forum suggest converting the data into a more manageable format, such as Excel or CSV, to facilitate plotting.

PREREQUISITES
  • Understanding of tight-binding models in solid-state physics.
  • Familiarity with Landau levels and their significance in graphene.
  • Proficiency in data manipulation using tools like Excel or CSV.
  • Basic knowledge of graphical plotting techniques in scientific research.
NEXT STEPS
  • Learn how to extract data from PDF files using tools like Tabula or Adobe Acrobat.
  • Research plotting techniques in Python using libraries such as Matplotlib or Seaborn.
  • Study the tight-binding model in detail to understand its application in graphene.
  • Explore the significance of magnetic fields on energy levels in condensed matter physics.
USEFUL FOR

Physics students, researchers in condensed matter physics, and anyone involved in the study of graphene and its electronic properties will benefit from this discussion.

Welcome to the PF.

What is the source of your data? What format is your data in? What word processing software is you thesis in?
 


Thank you for your reply!

Please give me your e-maıl address , ı send you source of my data ...
 


I am a student in ankara university in Turkey master degree at physics depratment.
My thesis subject is graphene ribbon and Landau Energy Bands of Graphite.

ı am using thıs artıcle that name is The electronic properties of graphene .(A.H. Castro Neto F.Guınea january 2009 )I am trying to plot graphics in Graphite ribbon Page 21 Figure 21.. (Fourteen Energy levels of tight-binding electrons in graphene in the presence of a magnetic flux)but I couldn't plot graphic exactly .Can you give me information how I can draw the graphics of figure 21 .

<< e-mail address deleted by berkeman >> my e-mail address . Please you send me e-mail .. then ı send you . I very difficult situation of this matter.. thanks..

Sorry graf, we do not allow posting of personal e-mail addresses in the open forums -- it attracts spam bots, and there are other privacy issues.

What format is the data in? Excel? CSV? What? And why is it hard to plot?

ok ı understand ..my data is artıcle (pdf) .ıts very dıffıcult for me .I try to plot graphıcs a lot but ı couldn't ..ıts very ımportant for me . my thesis will finish thıs perıod but ı couldn't it .. so that reason my thesıs will not finish and couldn't start a PhD this period.(

So it sounds like it's not "your" data -- it is data in PDF format from another person's original article? Can't you just type the data into Excel and graph it?
