Direct observation of large strain through van der Waals gaps on epitaxial B i2 T e3 /graphite : Pseudomorphic relaxation and the role of B i2 layers on the B ix T ey topological insulator series
Layered materials can usually grow without strain on top of distinct substrates if the only interaction between them is due to van der Waals forces. In such a scenario it would be expected that the heterointerface made up of weak bounds would not affect the overlayed material significantly for several large lattice-mismatched systems. Here we have studied the first stages of the heteroepitaxial gr
