Heat capacity in a quantum-dot superlattice with the Zeeman effect

We investigate the heat capacity using the previous theoretical framework for the electronic system in the quantum-dot superlattices (QDSL’s), including the Zeeman effect of GaAs, InAs, and InSb, respectively, by using an isotropic parabolic potential under a magnetic field on the basis of canonical...

Description
Summary:We investigate the heat capacity using the previous theoretical framework for the electronic system in the quantum-dot superlattices (QDSL’s), including the Zeeman effect of GaAs, InAs, and InSb, respectively, by using an isotropic parabolic potential under a magnetic field on the basis of canonical ensemble statistics. We numerically study the dependences of the heat capacity on the confinement frequency of the isotropic parabolic potential and the electronic density as functions of the temperature and the magnetic field strength in the QDSL’s of GaAs, InSb, and InAs, respectively. Furthermore, we numerically obtain the dependences of the heat capacity on the effective g-factor value in the QDSL’s of GaAs, InSb, and InAs, respectively, as functions of the temperature and the magnetic field strength.
