Re: [SIESTA-L] DOS is not in accordance with the band structure

Dear Zhiyong,

you can try to reduce the broadening to 0.005, 0.120 is 
(maybe) to high, and increase the number of points to 2000, but it may not 
help. Also, sometimes a shift of the kpoints can help (not always). 

I have the same problem  very frequently, the DOS is not in accordance with the 
band structure, even if I use 1 kpoints and very small broadening. After 
some analysis and tests with other software we concluded that we can trust the 
band structure. The DOS alone can give you wrong results. 

Perhaps somebody with more experience (than me) with Siesta can help.

Best regards,

   pablo
