... is a key underlying order parameter in materials that exhibit properties such as ferroelectricity, piezoelectricity, and magnetostriction. The Landau–Ginzburg expansion of Gibbs free energy details out the relation between the free energy and thermodynamic parameters and their respective canonical...

... is an interesting property in a given material that arises due to its coupling between two important functional properties like electrical and magnetic property. Conventionally, both electric polarization and magnetization were dealt as mutually exclusive properties due to their origin in materials. The coupling...

... as that of the electric field due to the polarization can be controlled by applying external stimuli such as stress and an external electric field. Furthermore, the application of strain can cause a property called flexoelectricity, which is a strain-induced electrical polarization. The domain structure and domain wall...

... , In general, physical quantities that describe intrinsic physical properties of a crystal defines a cause-effect relation between two measured quantities. For example, electric permittivity is a second-rank tensor property of a material that describes a cause-effect relation between applied electric field...

... of a ferroelectric is a summation of bulk free energy density that describes the bulk properties of crystallographically distinct paraelectric and ferroelectric phases, electrostatic energy that arises due to internal dipole-dipole interactions and externally applied electric field, and elastic energy that arises...

... phenomena exploitation and matter properties which are known to arise at different magnetic, optical, optical, mechanical, electrical, chemical and physical properties. It is employed to improve the efficiency of energy generation of photovoltaics (PVs) to develop new techniques for generating energy...

... life, we come across a wide range of materials and tuning their physical or chemical properties is often desired for better suitability and improved performance for specific applications. This is usually achieved by changing the thermodynamic conditions like pressure or temperature, or by applying...

... growth and its impact on the physical, electronics and electrical properties of group IV and III–V compound semiconductors. As group IV semiconductors, viz., Si, Ge, and SiGe have been studied extensively over the last 5 decades, we have primarily focused on the III-Nitride compound semiconductors...

... into electricity. In contrast, photo-thermal power generation uses a vast field of heliostats to transform solar energy into electrical energy. In the middle of the field, a thermal collecting tower is where the heliostat concentrates the sun’s rays. It directly or indirectly generates water vapor by heating heat...

... in the system. Thus, the ME effect could be realized in composites through the mediation of a linking property across the phases. Thus, the ME coupling in these composites could arise due to (a) strain mediated (b) charge mediated and (c) spin-mediated coupling between the order parameters. In the current...

... and You, 2019 ) in areas such as artificial intelligence and optimization, or being employed for fault diagnosis for electrical power systems using quantum annealing-assisted deep learning ( Ajagekar and You, 2021 ). It has also been explored for control [e.g., with model predictive control using quantum...

... as conventional substances. The selected thermodynamic property method is the UNIFAC-Lei model. The required group surface area and volume parameters and binary interaction parameters are manually input and calculated. The results are shown in Fig. 3.10 . The results show that the simulated values of the EQ...

... is extremely sensitive to atmospheric temperature and solar radiation intensity ( de Jong, 2013 ). Changes in PV cell performance can potentially lead to high electric stresses in PV panels and result in PV systems with highly variable or uncontrollable power generation capabilities. As a result...

... time ( Cohen, 1956 ). Also, in the field of electricity, Coulomb began to treat electrical phenomena as equations by suggesting F = kQq/r², similar to the form of gravitational force. To summarize, the achievements of Kepler, Galileo, Descartes, Huygens, and Newton...

... in designing MEMS/NEMS (Micro/Nano electrical mechanical systems) devices. Scaling laws are particularly useful in studying how different properties of a system change as its characteristic length is varied. For example, for an object of length l, its area scales as l², and its...
