Density Dependent Exchange Contribution to @ =@n and Compressibility in Graphene
We calculate @ =@n (where chemical potential and n electron density), which is associated with the compressibility, in graphene as a function of n, within the Hartree-Fock approximation. The exchange-driven Dirac-point logarithmic singularity in the quasiparticle velocity of intrinsic graphene disappears in the extrinsic case. The calculated renormalized @ =@n in extrinsic graphene on SiO2 has ...
متن کاملEffects of interactions and disorder on the compressibility of two-dimensional electron and hole systems
The compressibility w of dilute two-dimensional electron and hole gases in GaAs semiconductor structures has been studied in the ranges of the interaction parameter rs 1⁄4 1–2.5 and rs 1⁄4 10–30 for the electron and hole system, respectively. Nonmonotonic dependence of w 1 with an upturn at low carrier densities is observed. Despite the large difference in rs the behavior of w 1 in both systems...
متن کاملTemperature-dependent transport in suspended graphene.
The resistivity of ultraclean suspended graphene is strongly temperature (T) dependent for 50.5 x 10(11) cm(-2), the resistivity increases with increasing T and is linear above 50 K, suggesting carrier scattering from acoustic p...
متن کاملMathematical Modeling of the Temperature-Dependent Growth of Living Systems
In this investigation a non-equilibrium thermodynamic model of the temperature dependent biological growth of a living systems has been analyzed. The results are derived on the basis of Gompertzian growth equation. In this model, we have considered the temperature dependent growth rate and development parameter. The non-equilibrium thermodynamic model is also considered for exploring the variat...
