Irradiation-induced broadening of the Raman spectra in monolayer graphene
I. Shlimak, A. Butenko, E. Kogan +1
Broadening of the Raman scattering (RS) spectra was studied in monolayer graphene samples irradiated with various dose of ions followed by annealing of radiation damage at differen…
Charge carrier transport asymmetry in monolayer graphene
Erez Zion, Alexander Butenko, Amos Sharnoi +2
The conductivity and Hall effect were measured in CVD-grown monolayer graphene as a function of the gate voltage, , at temperatures down to = 2 K and in magnetic fields…
Critical behaviour of anisotropic magnets with quenched disorder: replica symmetry breaking studied by operator product expansion
E. Kogan, M. Kaveh
We study critical behaviour of disordered magnets near four dimensions. We consider the system with explicit cubic anisotropy and scalar disorder and that with random direction of…
Replica symmetry breaking for anisotropic magnets with quenched disorder
E. Kogan, M. Kaveh
We study critical behaviour of a magnet with cubic anisotropy and quenched scalar disorder which is taken into account by replica method. We derive to first order in approximat…
Localized magnetic moments in a Dirac semimetal as a spin model with long--range interactions
Eugene Kogan, Moshe Kaveh
We connect between the problem of thermodynamics of localized magnetic moments in a Dirac semimetal, the interaction with relativistic electrons leading to the effective ferromagne…
Density-dependent thermopower oscillations in mesoscopic two-dimensional electron gases
Vijay Narayan, Eugene Kogan, Chris Ford +6
We present thermopower and resistance measurements on GaAs-based mesoscopic two-dimensional electron gases (2DEGs) as functions of the electron density . At high …
