摘要：
The thermodynamic properties of bilayer graphene under dual gating have been studied as a function of temperature in the presence of an external perpendicular magnetic field. AB-stacked bilayer graphene quantum dots are investigated, and the energy levels are determined both without and with an applied magnetic field. Numerical expressions for mean energy, specific heat, magnetization, entropy, and susceptibility are calculated using the partition function. Specific heat showed a peak in the presence of a magnetic field, while magnetic susceptibility exhibited positive values in region 2, influenced by Landau levels and magnetic field effects.
