A huge range of different factors can affect the physical properties

 materials are notoriously sensitive to growth conditions, processing techniques and even sustained  measurement over multiple thermal cycles. A huge range of different factors can affect the physical properties of a 2D heterostructure including twist angle, strain, defects, external crystal alignment and pressure, all of which are near impossible to replicate between samples

Then came a talk by Cecilia Mattevi on growing 2D crystals. In the growth process, the specific reactor architecture is important, and often equipment is “home-made” by a research group. She suggested that using standardised, commercially available equipment would reduce variability. Another important consideration is the type of raw ingredients (precursors) used and a deep understanding of how this affects the samples remains an open question.
