• Quantum-dot superlattice
• Heat capacity
• Zeeman effect
• Tilted magnetic field

Extending our previous theoretical framework, we study the heat capacity of a canonical ensemble, including the Zeeman effect, under an incident magnetic field at a specific angle with respect to the axis of the quantum-dot superlattices (QDSL's) and confined by an isotropic parabolic potential for GaAs, InAs, and InSb, respectively. Furthermore, we numerically obtain the dependences of the heat capacity on the angle between the incident magnetic field's direction and the superlattice axis for an isotropic, confining, parabolic potential as functions of the temperature, the effective g-factor value, and the confinement frequency in the QDSL's of GaAs, InSb, and InAs, respectively. Particularly, the dependence of the heat capacity on the angle of the incident magnetic field is discussed in detail.
