We utilized a metal tantalum (Ta) ball-probe to measure the electrical properties of vertical-aligned one-dimensional (1D) nickel-oxide (NiO) nanorods. The 1D NiO nanorods (on average, ~105 nm wide and ~700 nm long) are synthesized using the hot-filament metal-oxide vapor deposition (HFMOVD) technique, and they are cubic phased and have a wide bandgap of 3.68 eV. When the 1D NiO nanorods are arranged in a large-area array in ohmic-contact with the Ta ball-probe, they acted as many parallel resistors. By means of a rigorous calculation, we can easily acquire the average resistance RNR and resistivity ρNR of a single NiO nanorod, which were approximately 3.1 × 10(13) Ω and 4.9 × 10(7) Ω.cm, respectively.
我们使用金属钽（Ta）球形探针来测量垂直排列的一维（1D）氧化镍（NiO）纳米棒的电学性质。一维NiO纳米棒（平均宽度约为105 nm，长度约为700 nm）采用热丝金属氧化物气相沉积（HFMOVD）技术合成，它们为立方相，具有3.68 eV的宽带隙。当一维NiO纳米棒以大面积阵列形式与Ta球形探针形成欧姆接触时，它们起到了许多并联电阻的作用。通过严格计算，我们可以轻松获得单个NiO纳米棒的平均电阻RNR和电阻率ρNR，分别约为3.1×10(13) Ω和4.9×10(7) Ω·cm。
