摘要

Zn-IV-N2半导体家族代表了光伏和照明应用中潜在的富地元素替代品,预计带隙范围为~0.6至~5 eV。虽然已经成功地合成了含Ge和Si的家族成员,但对带隙能量较低的成员,特别是ZnSnN2知之甚少。在这里,我们使用等离子体辅助分子束外延技术报道了这种化合物的生长,并将实验光学和结构特性与密度泛函理论预测进行了比较。

ZnSnN2: A new earth-abundant element semiconductor for solar cells
The Zn-IV-N2 semiconductor family represents a potential earth abundant element alternative for PV and lighting applications, with a predicted band gap range of ~0.6 to ~5 eV. While the Ge and Si containing members of the family have been successfully synthesized, little is known about the lower band gap energy members, in particular ZnSnN2. Here, we report the growth of this compound using a plasma-assisted molecular beam epitaxy technique, and compare experimental optical and structural properties to density functional theory predictions.
