plotting the band structure using the KP

[behnmafarzin]

Please, confirm the following:

• [*] I have checked Solcore’s documentation and could not find the answer.
• [*] I haven’t found any other issue on a related topic.

What’s the question?
The provided code in Solcore for plotting the band structure and effective masses of InGaAs is only capable of plotting the effective masses for different compositions and is unable to plot the band structure as mentioned in Solcore. I changed to graph=True on line 14, however, the other error appears in the result.

Additional information
The related code is here.
