“…Studying the photoelectric conversion properties of low-dimensional materials is of paramount importance for the properties of polarons [4][5][6]. Researchers have recently found that when external electric fields [7][8][9], magnetic fields [10][11][12], and Coulomb impurity fields [13][14][15] have a strong influence on the polaron effect, new polaron structures such as electric field polaron, magnetic field polaron, and impurity polaron appear. These new polaron structures have unusual significance for exploring quasiparticles in low-dimensional materials and have been of interest for potential applications in fabricating semiconductor devices [16].…”

Polaron phenomenon is abundant in low-dimensional semiconductor materials and is known to have unique effects on conductive material properties. Furthermore, phonon dragging action, which leads to polaron energy level, is less than the electron energy level. A decay magnetic field also affects the polaron effect, which causes polaron energy level changes. We demonstrated the unique electron-phonon coupling properties of this polaron using numerical calculations. Our findings have strong implications for theories of polaron properties and provide compelling evidence for a semiconductor device that industrial manufacturers use for new low-dimensional materials.

“…The solutions of the Schrödinger equation (SE) have been obtained analytically with different potential energy models. Expressions for the bound-state energies have been successfully used to investigate the thermodynamic, optical, magnetic and other physical properties of substances [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

In this study, a diatomic molecule interacting potential such as the deformed Schiöberg oscillator (DSO) have been applied to diatomic systems. By solving the Schrödinger equation in the with the DSO, analytical equations for the energy eigenvalues, molar entropy, molar enthalpy, molar Gibbs free energy and constant pressure molar heat capacity were obtained. The obtained equations were used to analyze the physical properties of diatomic molecules. With the aid of the DSO, the percentage average absolute deviation (PAAD) of computed data from the experimental data of the 7Li2 (2 3Πg), NaBr (X 1Σ+), KBr (X 1Σ+) and KRb (B 1Π) molecules are 1.3319%, 0.2108%, 0.2359% and 0.8841%, respectively. The PAAD values obtained by employing the equations of molar entropy, scaled molar enthalpy, scaled molar Gibbs free energy and isobaric molar heat capacity are 1.2919%, 1.5639%, 1.5957% and 2.4041%, respectively, from the experimental data of the KBr (X 1Σ+) molecule. The results of the energy spectra and thermodynamic properties are in good agreement with literature and available experimental data on diatomic molecules.

In the present enquiry, an in‐depth analysis of internal energy, entropy, heat capacity, and Helmholtz free energy of GaAs quantum dot (QD) which contains Gaussian impurity as dopant and falls under the influence of applied Gaussian white noise (GWHN) is performed. GWHN takes additive and multiplicative routes for its entrance to the doped QD. In this study, highly delicate and complex interplay between temperature, presence/absence of GWHN, mode of incorporation of GWHN, and the particular physical parameters concerned is unveiled. The said interplay, in effect, designs the features of the thermal properties. The enquiry uncovers competitive behavior between thermal disorder and spatial disorder that also affects the said thermodynamic properties.
