Pradeep Mutalik tackles the interesting topic of moiré patterns, the point in which light and dark elements collide. What is happening, and why graphene acts in this way are looked at. Case studies help to get your senses acclimated to the moiré patterns.
 
Key Takeaways:
 
  • Overlapping two similar grids using their light and dark elements result in magical outcomes where new sinuous patterns emerge.
  • Created from light and dark elements, moiré patterns and are common in scientific work.
  • Moiré patterns are being used in fields of study that include marine engineering, optics, art and photography for detecting fake banknotes.
 
“This large hexagonal superlattice enables large numbers of electrons to interact, with interesting results, especially when the layers are rotated at specific angles at which, apparently, quantum tunneling can occur.”
