Abstract
Abstract Density functional and many-body perturbation theories have been employed to investigate the superconductive character and transport properties in 2D buckled aluminene. The examination of superconductivity at low temperature reveals a huge dependence on the electron phonon coupling (EPC), especially in the calculation of the critical temperature by the Allen-Dynes theory. It is found that the EPC strength is dominated by the longitudinal and transversal optical phonon. The superconducting gap equals to 1.5 meV at 0 K, drops to 0 meV for temperatures above the critical temperature. Transport properties calculations reveals a carrier's mobility of 8842.6 c m 2 V − 1 s − 1 at 100 K which decreases to 620 c m 2 V − 1 s − 1 at room temperature. The findings of this work highlight the importance of aluminene as a promising candidate for future advanced applications.
