Dear Sir/Madam,

first of all, I would like to thank you to have developed and made ​​available online this tool. Currently, I’m interested in the study of the band structure of InAs UTB devices. There seems to be a bug in the program. The bottom of the conduction band of the first subband is not calculated. This error leads to a discontinuous band structure. To clarify what I mean you can look the graphs that I uploaded in this link https://www.dropbox.com/s/rw6bp4nj2rbv2yh/nanoHub.zip Do you know this bug? Do you have any suggestions for me?

Kind regards, Enrico
