Also if you prefer other names for the functions I don't mind, Thomas used `composite`, I don't know which one is better.

Also, for the name: It is not really a `heterojunction` but potentially several `heterojunctions`, so probably calling it `heterojunction` would not picture what the function does exactly.

Well in that case you might as well build the section object yourself instead of passing a dict :)

However would you then introduce the `open` parameter? That forces the user to replace a list with a dict just to change the configuration.

The imaginary number seems natural to me. `2j` is just `2` shifted by a phase :)

Another option could be using negative numbers (`-2` instead of `2j`)

Oooh ok I understand now, so ```python graphene_nanoribbon([(7, 2), (11, 2)], open_start=True) # or invert=True ``` would be the old ```python graphene_nanoribbon([(7, 2j), (11, 2)]) ``` ? I like it...
