Synthesis, structural and optical properties of ZnS/ZnO heterostructure-alloy hexagonal micropyramids

Heterostructure alloys with controlled structure and composition are essential for future electronics and optoelectronics. While heterostructure formation creates sharp electronic junction, alloying allows bandgap tunability. Herein, ZnS/ZnO heterostructure-alloy hexagonal micropyramids are grown on...
