“…This is because the occupation probability of the levels changes with the temperature rising and the mean energy value monotonically increasing, demonstrating nonlinear behavior at sufficiently high temperatures. Similar behavior has been reported in [26,27].…”

“…Numerical calculations are performed to determine the sum in the partition function. The number of states to be considered is obtained by examining the dependence of the partition function on the number of states, as shown in a previous study [26,36]. For each case, we identify the number of states that need to be considered, after which the values of the partition function do not vary significantly.…”

“…In [24,25], core/shell nanofiber or transitionmetal dichalcogenides (TMD) monolayers were considered as the system to investigate statistical properties. Alternately, such effects are also investigated in quantum dots [26][27][28]. However, it is interesting to study statistical properties in NPLs, by considering the hybrid nature of the spectrum, especially the fact that polarization effects are strongly pronounced.…”

This paper theoretically studies the impurity states and the effect of impurity concentration and configuration on the optical, electrical, and statistical properties of CdSe nanoplatelets (NPLs). The image charge-based model of electron–impurity interaction has been proposed. The charge carrier energy spectra and corresponding wave functions depending on impurity number and configuration have been calculated. The electron binding energies have been calculated for different NPL thicknesses. It has been shown that the image charges-based interaction potential that arises due to the dielectric constants mismatch is much stronger than the interaction potential that does not take such a mismatch into account. Also, it has been demonstrated that binding energies are increasing with the number of impurities. We calculated the canonical partition function using the energy levels of the electron, which in turn is used to obtain the mean energy, heat capacity, and entropy of the noninteracting electron gas. The thermodynamic properties of the noninteracting electron gas depending on the geometric parameters of the NPL, impurity number, configuration, and temperature have been studied.

“…The problem was solved via the exact diagonalization method [43,44]. In another consideration, Khordad and his collaborators in 2019 investigated the statistical properties of a GaAs QD with an effective-PP [45]. The selected statistical quantities of the QD evaluated via CEA in the presence of a B -field and its interaction with the electron spin.…”

In this study, the Schrodinger equation (SE) with screened Kratzer potential (SKP) in the presence of external magnetic and AB-flux fields is investigated using the factorization method.The eigenvalue and eigenfunction for the system are obtained in closed form. It is found that the present of the magnetic field partially removes the degeneracy when the screening parameter of the potential was small   0.005   but the addition of the AB field removed the degeneracy faster and better. The magnetization and magnetic susceptibility of the system are evaluated at zero and finite temperatures and other thermodynamic properties of the system are discussed.More so, the presence of the AB-flux field makes the system to exhibit a both a paramagnetic and diamagnetic behavior. A straight forward extension of these results to three dimension shows that the present result is consistent with those obtained in literature.
