Hi Padmaja, Please, study the example05 example05: This example shows how to use pw.x and postprocessing codes to make a contour plot in the [110] plane of the charge density for Si, and to plot the band structure of Si.
The code is not aware of the name of the symmetry points (as far as I know). You should. If you are studying a cubic material, you can find the names and coordinates of the high symmetry points in a solid state physics or semiconductor textbook or in one of the hundreds of articles on band calculations. If your crystal has a not so usual lattice, you can use the names defined in the book The Mathematical Theory of Symmetry in Solids: Representation Theory for Point Groups and Space Groups [image: Cubierta delantera]<http://books.google.com/books?id=lMdNv_wbu2IC&printsec=frontcover&hl=es&source=gbs_ge_summary_r&cad=0> Christopher Bradley<http://www.google.com/search?hl=es&tbo=p&tbm=bks&q=+inauthor:%22Christopher+Bradley%22>, Arthur Cracknell<http://www.google.com/search?hl=es&tbo=p&tbm=bks&q=+inauthor:%22Arthur+Cracknell%22> http://books.google.com/books?id=lMdNv_wbu2IC&printsec=frontcover&dq=bradley+symmetry&source=bl&ots=Nle4sptJFT&sig=68EASNmZCFBcppbWHbe3_1gSq0c&hl=es&ei=X5W5TYDRBIfe0QGLsaTgDw&sa=X&oi=book_result&ct=result&resnum=1&ved=0CBYQ6AEwAA#v=onepage&q&f=false or define your own names, i.e, A,B,C, ... , specifying the coordinates of the points. Personally I do not like the postscript file generated with plot bands. I generally use the data file, and make my band diagram with gnuplot (a heavy of work). If you just want to add the letters, you may edit the postcript file. pstoedit - f xfig file.ps file.fig edit it with xfig, and export to EPS. ---------- Mensaje reenviado ---------- From: Padmaja Patnaik <padmaja_patn...@yahoo.co.uk> To: pw_forum at pwscf.org Date: Thu, 28 Apr 2011 05:34:15 +0100 (BST) Subject: [Pw_forum] About band plot Hi All I had put this query last tuesday but didnt get any response. Thats why asking it again. While plotting band structure, in the output ps file the code doesn't mention the high symmetry points Gamma, K, L etc. along the X axis. How to do that?
