This paper proposes an obliquely aligned InN nanorod array to maximize nanorod deformation in the application of nanopiezotronics. The surface-dependent piezotronic I-V characteristics of the InN nanorod array with exposed polar (0002) and semipolar ( ̅1102) planes were studied by conductive atomic force microscopy. The effects of the piezopotential, created in the InN under straining, and the surface quantum states on the transport behavior of charge carriers in different crystal planes of the InN nanorod were investigated.

- Gallium implantation in ZnO using a focused-ion beam creates an effective mask for dry etching with hydrogen, optimizing etch stop properties.
- The best mask quality is achieved at a fluence of 2.8 × 10(16) cm(-2), while lower and higher fluences lead to poor selectivity and surface damage, respectively.
- Transmission electron microscopy shows that Ga(+) ions can be incorporated into ZnO without forming additional phases up to this optimal fluence, while higher fluences result in the formation of surface particles, specifically ZnGa(2)O(4), which also contribute to etching behavior.
