Diffusion characterization of antimony-based type-II superlattices using electron beam induced current and time-resolved photoluminescence
… using electron beam induced current (EBIC) and time-resolved photoluminescence (TRPL) technologies. Moreover, we investigate how the molar composition of antimony and gallium affect on the diffusion characteristics of this materials.

Characterization and modeling of CdCl2 treated CdTe/CdS thin-film solar cells
… University. In order to investigate the optimal time of CdCl2 treatment, sample solar cells were tested for microstructural and performance properties. Device microstructure was analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), and atomic force microscopy (AFM). Device …

Crescita epitassiale e caratterizzazione di un epi-layer spesso di 4H-SiC per la rivelazione di neutroni
… La fotoluminescenza risolta nel tempo (TRPL) è stata utilizzata per stimare il tempo di vita dei portatori sull'intero strato epitassiale di 250 micron utilizzando diverse lunghezze d'onda per ottenere informazioni da diverse profondità. Inoltre, è stata condotta un'analisi dei …
