Preparation, Chemical Composition, and Optical Properties of (β–Ga2O3 Composite Thin Films)/(GaSxSe1−x Lamellar Solid Solutions) Nanostructures

SPRINCEAN, Veaceslav; LEONTIE, Liviu; CARAMAN, Iuliana; LUPAN, Oleg; ADELING, Rainer; GURLUI, Silviu; CARLESCU, Aurelian; DOROFTEI, Corneliu; CARAMAN, Mihail (MDPI, Basel, Switzerland, 2023)

GaSxSe1−x solid solutions are layered semiconductors with a band gap between 2.0 and 2.6 eV. Their single crystals are formed by planar packings of S/Se-Ga-Ga-S/Se type, with weak polarization bonds between them, which ...
