“…The flakes can easily be detected from the images; their surface areas are around 1 µm 2 or more, and their thicknesses are about 50-100 nm. The same results have been found in the literature for ZnO sheets or flakes formed by the electrodeposition technique [22,23]. The surfaces of the ZnO are homogeneous with flakes and compatible with interlayer applications.…”

ZnO flake interlayers were fabricated by the electrochemical deposition technique on p-Si to obtain Au/ZnO/p-Si heterostructures for Schottky-type photodiode applications and to test the capacitive performance of the structures. ZnO flake structures were investigated by x-ray diffractometry and scanning electron microscopy measurements, and their crystalline and flake-like structures were confirmed. The Au/ZnO/p-Si heterostructures were characterized by current–voltage (I–V) measurements for various illumination densities of light from dark to 150 mW cm−2. Various heterostructure parameters such as the ideality factor, barrier height, series resistance and rectifying ratio (RR) values were determined by I–V characteristics. The heterostructure exhibited a high RR of 6.85 × 103. The detection parameters revealed 0.49 mA W−1 responsivity and 2.69 × 109 Jones specific detectivity values. Furthermore, capacitance–voltage (C–V) measurements were employed to obtain the capacitive behavior of the Au/ZnO/p-Si heterostructure at various frequencies. Based on these results, Au/ZnO/p-Si heterostructures have potential for photodiode applications.
