SUMMARY:Twistronics: A Recent Avenue in van der Waals Heterostructures
LOCATION:Online
DESCRIPTION;ENCODING=QUOTED-PRINTABLE:Seminar \n\non\n Twistronics: A Recent Avenue in van der Waals Heteros
 tructures\nby\nDr. Pramoda Kumar Nayak,IIT-Madras\n \non\nMonday, 21 Jun 20
 21\nTime:3:00pm\n\n\n \nAbstract:\n\nAfter the discovery of graphene i
 n 2004, many other 2D crystals have been identified, often with intriguing 
 properties that have no counterparts in three-dimensional solids. Even if i
 ndividual 2D materials own various interesting and unexpected properties, t
 he stacking of such layers leads to ‘artificial vdW solids’ called as van d
 er Waals heterostructures (vdW HSs) that result in the emergence of new sta
 tes of matter with novel functionalities. The vdW HSs not only depend on th
 e combination of different 2D crystal but also on their rotational alignmen
 t opening the avenue for a new field called twistronics. Coupling between t
 he two layers depends on the stacking angle, which can be used as an extern
 al degree of freedom to tune their optical and electronic properties. In th
 is talk, I will cover the atlas of vdW materials and their heterostructures
  emphasizing on synthesis, characterization and potential applications in e
 lectronics and optoelectronics. Additionally, I will describe how a simple 
 twist can dramatically changes the functionalities of vdW HSs, fabricated f
 rom 2D monolayers grown by chemical vapor deposition. Finally, I will summa
 rize the current challenges and future opportunities in this emerging field

X-EXTRAINFO:Abstract:\nAfter the discovery of graphene in 2004, many other 2D crystals 
 have been identified, often with intriguing properties that have no counter
 parts in three-dimensional solids. Even if individual 2D materials own vari
 ous interesting and unexpected properties, the stacking of such layers lead
 s to ‘artificial vdW solids’ called as van der Waals heterostructures (vdW 
 HSs) that result in the emergence of new states of matter with novel functi
 onalities. The vdW HSs not only depend on the combination of different 2D c
 rystal but also on their rotational alignment opening the avenue for a new 
 field called twistronics. Coupling between the two layers depends on the st
 acking angle, which can be used as an external degree of freedom to tune th
 eir optical and electronic properties. In this talk, I will cover the atlas
  of vdW materials and their heterostructures emphasizing on synthesis, char
 acterization and potential applications in electronics and optoelectronics.
  Additionally, I will describe how a simple twist can dramatically changes 
 the functionalities of vdW HSs, fabricated from 2D monolayers grown by chem
 ical vapor deposition. Finally, I will summarize the current challenges and
  future opportunities in this emerging field.
