PeLED: Materials, Physics, and Numerical Simulation

This book presents an in-depth study of perovskite light-emitting diodes (PeLEDs), covering perovskite materials, the physical principles underlying the devices' operation, and their numerical modeling using SILVACO ATLAS software. It describes the various steps involved in simulating PeLED structures and analyzes the influence of several parameters-including the thickness of the active layer, temperature, and the composition of the materials CH¿NH¿PbBr¿, CH¿NH¿PbCl¿, and CH¿NH¿Pb(Br¿¿¿Cl¿)¿, on the electronic and optical characteristics of the devices. Particular attention is paid to electroluminescent performance, such as current-voltage characteristics, emission spectra, and full width at half maximum (FWHM), by comparing the numerical results with experimental data available in the literature. Intended for students, researchers, and engineers, this book serves as a scientific resource for understanding, modeling, and optimizing perovskite light-emitting diodes.
