image: Defect engineering is an effective strategy to modify 2D materials for enhanced HER activity. By structuring edge defects, vacancy defects and dopant derived defects, the electronic structure ...

Atomic vacancies are a type of point defect in a crystal lattice where one or more atoms are absent from their regular lattice positions. Although they might seem like simple imperfections, these ...

As a new member of photovoltaic family, antimony trisulfide (Sb2S3) has the satisfactory bandgap of 1.7eV, benefiting the fabrication of the top absorber layer of tandem solar cells. Due to special ...

Researchers have discovered a new way to tune the quantum properties of tiny defects in diamond—by gently stretching or compressing the crystal. These findings could pave the way for next-generation ...
