Later on, if someone writes a whole article on ferroelectric domain walls ( for example ), it's no problem, we can just update the link in the " generalized " article.
2.
Second, in a similar manner, certain ferroelectric materials can develop stripes consisting of parallel ferroelectric domains, where each domain acts like a photovoltaic and each domain wall acts like a contact connecting the adjacent photovoltaics ( or vice versa ).
