Study of drag resistivity in dielectric medium with the correlations effect
Abstract We study the drag resistivity numerically for charge carriers in a specially separated electron-electron (e-e) bilayer system for both the symmetric and asymmetric case in weak interaction and Boltzmann regime. Interaction in Coulomb drag effect is based on Coulomb interaction in a speciall...

| 520 | |a Abstract We study the drag resistivity numerically for charge carriers in a specially separated electron-electron (e-e) bilayer system for both the symmetric and asymmetric case in weak interaction and Boltzmann regime. Interaction in Coulomb drag effect is based on Coulomb interaction in a specially separated bilayer systems. Random phase approximation (RPA) method is used to find the drag resistivity. Simply RPA method is a reliable method for high-density regime where exchange and correlation effects do not impact too much. On lowering the density, the exchange and correlation effects are significant which are included by suggesting the local field correction (LFC) in effective interlayer interactions. The drag resistivity is noticed improvement on employing the LFC. Impact of exchange and correlation based LFC increase on increasing the temperature and decreasing the concentration. Predictable behaviour is shown by the dependency of drag resistivity on temperature, density, interlayer spacing, and dielectric constant. | ||

Study of drag resistivity in dielectric medium with the correlations effect |
| abstract |
Abstract We study the drag resistivity numerically for charge carriers in a specially separated electron-electron (e-e) bilayer system for both the symmetric and asymmetric case in weak interaction and Boltzmann regime. Interaction in Coulomb drag effect is based on Coulomb interaction in a specially separated bilayer systems. Random phase approximation (RPA) method is used to find the drag resistivity. Simply RPA method is a reliable method for high-density regime where exchange and correlation effects do not impact too much. On lowering the density, the exchange and correlation effects are significant which are included by suggesting the local field correction (LFC) in effective interlayer interactions. The drag resistivity is noticed improvement on employing the LFC. Impact of exchange and correlation based LFC increase on increasing the temperature and decreasing the concentration. Predictable behaviour is shown by the dependency of drag resistivity on temperature, density, interlayer spacing, and dielectric constant. © The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature 2021 |
