Intrinsic graphene
WebMar 16, 2024 · The intrinsic NPR υ 1 is obtained by fitting to ε 1 = − υ 1 ε 2 + υ 2 ε 2 2 + υ 3, where ε1 is the response strain driven by forced strain ε2. (B) The calculated Poisson’s ratio with respect to the applied strain along armchair direction. The pink area highlights the NPR area. The NPR is derived from ν = − ∂ ε 1 ∂ ε 2. WebWe find that crystalline defects intrinsic to TMDs induce substantial electronic scattering and charge carrier density fluctuations in the graphene. These signatures of local disorder explain the significant degradation of graphene device mobilities using TMD substrates, particularly compared to similar graphene on hBN devices.
