“…Over the past decade, several works have been done on the Rashba effect, both experimental and theoretical. An analytical method has been used to study the three-electron quantum dot in the presence of a spin-orbit interaction [48]. B.S and Akay have devoted their work to the pseudo-Zemann division in grapheme cones by magnetic field, and they have found that the magnetic field is useful for controlling the level of division in topological cones [49,50].…”

In this work, we investigate the cumulative effects of laser and spin-orbit interaction (SOI) on the thermodynamic properties of a quantum pseudo-dot using the Tsallis formalism, through the evaluation of the energy to derive some thermodynamic properties at the accessible states. From the results obtained, we found that contrary to the SOI, a laser field is a suitable external field to reduce the rate of entropy (disorder) in a quantum system, and thus, this allows control on the spin alignment and increasing the number of accessible states hence stabilizing our system, simultaneously reducing the rate of entropy due to the great effect of the laser field. Therefore, the combined effects of laser field and SOI are an important parameter to enhance the thermodynamic quantities and more define the spin alignment of quantum system.

“…In particular, some experimental studies on the photoluminescence and electrical properties of InAs and GaAs compounds, which will help to understand why they are so effective in solar cell applications, have been attracted [7][8][9][10]. Apart from these, there are many studies in the literature regarding the magnetic susceptibility and optoelectronic properties of such compounds [11][12][13].…”

In this study, the magnetic nature and also, electronic characteristics of Ga4X3Mn (X=P and As) systems, which have simple cubic structure confirming P4 ̅3m space group and 215 space number, have been reported. All calculations realized within the framework of ab initio simulation methods have been performed using the meta-generalized gradient (META-GGA) approach within the Density Functional Theory (DFT). In view of the energy-volume curves and the calculated cohesive and formation energies for considering four different types of magnetic orders, it has been detected that these compounds have A-type antiferromagnetic nature. Also, the examined electronic behaviors in the A-type antiferromagnetic order of the related systems show that all two compounds are semiconductors due to having small band gaps in their electronic band structures (Eg = 0.23 eV for Ga4P3Mn and Eg = 0.16 eV for Ga4As3Mn).

“…Gaussian QD has been investigated approximately for one particle problem by different authors (20)(21)(22)(23)(24)(25)(26)(27)(28). The variational and numerical diagonalization techniques have been applied to study the QD Hamiltonian, and investigate the electronic structure, magnetic and thermodynamic properties of a single (29)(30)(31) and coupled quantum dots (32)(33)(34).…”

The Energy Spectra and Heat Capacity of GaAs Gaussian Quantum Dot in an External Magnetic Field

2021

View full text Add to dashboard Cite

In this paper, a theoretical study of the energy spectra and the heat capacity of one electron quantum dot with Gaussian Confinement in an external magnetic field are presented. Using the exact diagonalization technique, the Hamiltonian of the Gaussian Quantum Dot (GQD) including the electron spin is solved. All the elements in the energy matrix are found in closed form. The eigenenergies of the electron were displayed as a function of magnetic field, Gaussian confinement potential depth and quantum dot size. Explanations to the behavior of the quantum dot heat capacity curve, as a function of external applied magnetic field and temperature, are presented.
