Abstract
In the present work, we have calculated the thermodynamic properties of an asymmetrical Gaussian potential quantum dot under external electric field. To this end, we have solved the Schr�dinger equation and have obtained the energy levels and wave functions, analytically. According to the obtained eigenvalues, we have calculated the partition function of the system by the Poisson summation formalism. Afterward, we have deduced some thermodynamic properties such as mean energy, entropy, specific heat and free energy under the application of an external electric field using the canonical ensemble approach. These thermodynamic properties for an asymmetrical Gaussian potential GaAs quantum dot have been discussed in detail.
期刊介绍：
High Temperatures – High Pressures (HTHP) is an international journal publishing original peer-reviewed papers devoted to experimental and theoretical studies on thermophysical properties of matter, as well as experimental and modelling solutions for applications where control of thermophysical properties is critical, e.g. additive manufacturing. These studies deal with thermodynamic, thermal, and mechanical behaviour of materials, including transport and radiative properties. The journal provides a platform for disseminating knowledge of thermophysical properties, their measurement, their applications, equipment and techniques. HTHP covers the thermophysical properties of gases, liquids, and solids at all temperatures and under all physical conditions, with special emphasis on matter and applications under extreme conditions, e.g. high temperatures and high pressures. Additionally, HTHP publishes authoritative reviews of advances in thermophysics research, critical compilations of existing data, new technology, and industrial applications, plus book reviews.
