Twisted bilayer graphene, a promising material for optoelectronic applications, offers several effective routes toward electronic structure engineering, for example via tuning the relative orientation of the two graphene layers or by varying the distance between them. The so-called collapsed wrinkles, standing, or folded, combine both of these properties. The mutual lattice alignment of the sidewalls of wrinkle leads to formation of a graphene superlattice. Using Raman spectroscopy, we show that the interaction between the sidewalls of the wrinkle and thereby the properties of the twisted multilayer wrinkle can be well tuned by temperature.
