Watson H, Ruocco A, Tiberi M, Muench J, Balci O, Shinde S, et al.
ACS Nano . 2024 Oct; 18(44):30269-30282. PMID: 39436682
Next-generation data networks need to support Tb/s rates. In-phase and quadrature (IQ) modulation combine phase and intensity information to increase the density of encoded data, reduce overall power consumption by...

Caridad J, Calogero G, Pedrinazzi P, Santos J, Impellizzeri A, Gunst T, et al.
Nano Lett . 2018 Jul; 18(8):4675-4683. PMID: 30029573
We show that polar molecules (water, ammonia, and nitrogen dioxide) adsorbed solely at the exposed edges of an encapsulated graphene sheet exhibit ferroelectricity, collectively orienting and switching reproducibly between two...

Gao Y, Kim S, Zhou S, Chiu H, Nelias D, Berger C, et al.
Nat Mater . 2015 Jun; 14(7):714-20. PMID: 26076304
Two-dimensional materials, such as graphene and MoS2, are films of a few atomic layers in thickness with strong in-plane bonds and weak interactions between the layers. The in-plane elasticity has...
