Silicene 1 is a single atomic layer of silicon (Si) much like graphene, the first example of an elemental two-dimensional (2D) nanomaterial whose study led to the 2010 Nobel Prize in Physics. 2 Until 2010 or so, the only known crystalline form of elemental silicon was the one with the so-called diamond structure (a three-dimensional [3D] cubic structure with sp 3 -bonded Si atoms). That silicon could potentially form a 2D structure was first postulated by Takeda and Shiraishi. 3 , 4 This early work and others, both theoretical 5 7 and experimental, 8 , 9 went mostly unnoticed until the prediction that silicene could have similar exotic properties as graphene by Guzmán-Verri and Lew Yan Voon in 2007, 1 and silicene nanoribbons were reported to have been fabricated on a silver substrate by Kara et al. in 2009. 10 Since then, the study of silicene has exploded, mainly theoretically 11 527 but also experimentally. 528 612
