IRG-2: 2D

Control of 2D Electronic Structure and 1D Interfaces by Surface Functionalization of Group IV Graphane Analogues

Two dimensional electronic systems offer rich possibilities for new phenomena and phases. Single atom thick materials composed of group IV atoms other than carbon IRG-2D_Nano CEM and OSUoffer exceptional  tunability of electronic materials. The atomic sheets readily bond atoms covalently, allowing controllable changes in the electronic structure of the sheet that lead to a rich variety of electronic characteristics. IRG-2 brings together diverse experience in materials development, 2D electronic properties, patterning, optical and transport characterization together with theory and modeling to bring these materials to fruition and study their rich physical properties.

 Spin relaxation mechanisms in graphene. An illustrative figure of three possible spin relaxation mechanisms for graphene: Elliott–Yafet, Dyakonov–Perel and resonant scattering by local magnetic moments. The blue dots indicate the electrons/holes with yellow arrows as their spin orientation. The red dots represent the scattering centres. Grey cones with circular arrows represent the spin precession

“The isolation of graphene has triggered an avalanche of studies into the spin-dependent physical properties of this material and of graphene-based spintronic devices. Here, we review the experimental and theoretical state-of-art concerning spin injection and transport, defect-induced magnetic moments, spin–orbit coupling and spin relaxation in graphene. Future research in graphene spintronics will need to address the development of applications such as spin transistors and spin logic devices, as well as exotic physical properties including topological states and proximity-induced phenomena in graphene and other two-dimensional materials.”
