Abstract

The unique structural features of many ternary nitride materials with strong chemical bonding and band gaps above 2.0 eV are limited and are experimentally unexplored. It is important to identify candidate materials for optoelectronic devices, particularly for light-emitting diodes (LEDs) and absorbers in tandem photovoltaics. Here, we fabricated MgSnN2thin films, as promising II–IV–N2semiconductors, on stainless-steel, glass, and silicon substrates via combinatorial radio-frequency magnetron sputtering. The structural defects of the MgSnN2films were studied as a function of the Sn power density, while the Mg and Sn atomic ratios remained constant. Polycrystalline orthorhombic MgSnN2was grown on the (120) orientation within a wide optical band gap range of ∼2.20–2.17 eV. The carrier densities of 2.18× 1020to 1.02 × 1021cm–3, mobilities between 3.75 and 2.24 cm2/Vs, and a decrease in resistivity from 7.64 to 2.73 × 10–3Ω cm were confirmed by Hall-effect measurements. These high carrier concentrations suggested that the optical band gap measurements were affected by a Burstein–Moss shift. Furthermore, the electrochemical capacitance properties of the optimal MgSnN2film exhibited an areal capacitance of 152.5 mF/cm2at 10 mV/s with high retention stability. The experimental and theoretical results showed that MgSnN2films were effective semiconductor nitrides toward the progression of solar absorbers and LEDs.
