Directionally Locked Heteroepitaxy with a Structurally Modulated van der Waals Material
Nitish Mathur, Guangming Cheng, Francesc Ballester +17
Precise orientation of symmetry-mismatched epilayers on van der Waals (vdW) substrates via heteroepitaxy has commonly been achieved through surface treatment processes to accommoda…
