Wide band gap p-type CuBO2 nanostructures by hydrothermal route and fabrication high quality p-CuBO2/n-ZnO nano-heterojunction

CuBO2 nanocubes were synthesized for the first time through hydrothermal route. Beside compositional, morphological, structural and optical studies of the materials, I–V characteristics of the fabricated p-CuBO2/n-ZnO was measured using conducting atomic force microscopy which showed excellent diode behavior with an ideality factor 1.03 and very small leakage current 0.04 nA.
