ZnO nanowires (NWs) are very attractive for a wide range of nanotechnological applications owing to their tunable electron concentration structural and surface defect engineering. A 2D electrical profiling of these defects is necessary to understand their restructuring dynamics during engineering processes. Our work proposes the exploration of individual ZnO NWs, dispersed on a SiO/p-Si substrate without any embedding matrix, along their axial direction using scanning capacitance microscopy (SCM), which is a useful tool for 2D carrier profiling.

A low-temperature hydrothermal process is employed for the growth of ZnO nanowires (NWs) on seedless Au surface. A more than two order of magnitude change in ZnO NW density is demonstrated via careful addition of NHOH in the growth solution.

- The study focuses on a new method for controlling the density of one-dimensional ZnO nanowires (NWs) using a low-temperature hydrothermal process on Au surfaces.
- Researchers found that varying the concentration of ammonium hydroxide in the solution can change the density of the NWs significantly.
- The research also shows how these density changes affect the electrical properties of the NWs, revealing potential for tailored applications in electronic devices.
