Negative Thermal expansion of pure and doped Graphene
Sarita Mann, Ranjan Kumar, V. K. Jindal
Graphene and its derivatives distinguish themselves for their large negative thermal expansion even at temperatures as high as 1000K. The linear thermal expansion coefficients (LTE…
Thermodynamic properties of pure and doped (B, N) graphene
Sarita Mann, Pooja Rani, Ranjan Kumar +2
Ab-initio density functional perturbation theory (DFPT) has been employed to study thermodynamical properties of pure and doped graphene sheet and the results have been compared wi…
Temperature and field dependence of thermally activated flux flow resistance in Bi2Sr2CaCu2O8+δ superconductor
Devina Sharma, Ranjan Kumar, V. P. S. Awana
We study the temperature dependence of the resistivity as a function of magnetic field in superconducting transition (Tconset - TcR=0) region for different Bi2Sr2CaCu2O8+δ supercon…
Comparative experimental and Density Functional Theory (DFT) study of the physical properties of MgB2 and AlB2
Devina Sharma, Jagdish Kumar, Arpita Vajpayee +3
In present study, we report an inter-comparison of various physical and electronic properties of MgB2 and AlB2. Interestingly, the sign of S(T) is +ve for MgB2 the same is -ve for…
