Micrometer-sized NiCo2O4 platelets are prepared from their corresponding hydroxide precursor. Then, the electrical transport within an individual NiCo2O4 nanoplate is investigated. The mechanisms of electrical conduction in the low-temperature range (T < 100 K) can be explained in terms of the Mott's variable-range hopping model. At high temperatures (T > 100 K), both the variable-range hopping and nearest-neighbor hopping mechanisms contribute to the electrical transport properties of the NiCo2O4 nanoplate.
