In this work we execute computational calculations to investigate the structural, electronic and magnetic properties of the GaN/MnN/GaN and MnN/GaN/MnN interlayers. The calculations were carried out by a method based on pseudopotentials, as implemented in the Quantum ESPRESSO code. For the description of the [...]

Improved light output power in GaN-based vertical light-emitting diodes with p-AlInGaN/GaN superlattices
We report the effect of p-type AlGaInN/GaN superlattices (SLs) as electron-blocking layers (EBLs) on the optical properties of vertical light-emitting diodes (VLEDs). Using p-AlGaInN/GaN SLs in VLEDs, we have achieved significant improvements in [...]

Enhanced Continuous-wave Trahertz emission by nano-electrodes in a photoconductive photomixer
Semiconductor materials used as PCA-based photomixers must exhibit high resistivity, high carrier mobility and ultrashort carrier lifetime. Low-temperature-grown GaAs (LT GaAs) has been shown to have such characteristics 14–18 . The samples used in our experiment had [...]
