Anisotropy of Light Emission from the Surface LED Based on the Type-II ZnSe/BeTe Heterojunction

Abstract

Electroluminescence (EL) spectra are studied in the type-II ZnSe/BeTe light emitting diode (LED) based on a single heterojunctions. The light emitted from the surface exhibits a strong in-plane linear polarization along 110 crystal axis. The polarization is stable in respect to an increase of the applied voltage and temperature tip to 300 K. The experimental data are discussed in the framework of a tight-binding model taking into account a type-II band alignment and lack of common atom in the ZnSe/BeTe heterosystem.
