The Transfer Matrix Method and The Theory of Finite Periodic Systems. From Heterostructures to Superlattices
Pedro Pereyra
Long-period systems and superlattices, with additional periodicity, have new effects on the energy spectrum and wave functions. Most approaches adjust theories for infinite systems…
On the transmittance of metallic superlattices in the optical regime and the true refraction angle
Pedro Pereyra
Recently, an approach for metallic superlattices based on the finite periodic systems theory was introduced \cite{Pereyra2020}. Unlike most, if not all, of the published approaches…
Why the effective-mass approximation works so well for nano-structures
Pedro Pereyra
The reason why the effective-mass approximation, derived for wave packets constructed from infinite-periodic-systems' wave functions, works so well with nanoscopic structures, has…
Charge polarization effects on the optical response of blue-emitting superlattices
Pedro Pereyra, Fatna Assaoui
In the new approach to study the optical response of periodic structures, successfully applied to study the optical properties of blue-emitting InGaN/GaN superlattices, the spontan…
New approach to study light-emission of periodic structures. Unveiling novel surface-states effects
Pedro Pereyra
An accurate approach to calculate the optical response of periodic structures is proposed. Using the genuine superlattice eigenfunctions and energy eigenvalues, the eigenfunctions…
Improved optical transitions theory for superlattices and periodic systems; new selection rules
Pedro Pereyra
Using the superlattice (SL) eigenvalues and eigenfunctions , obtained within the theory of finite periodic systems, where indicates the subban…
