The validity of our local conductivity density analysis method is shown by using a GaN cluster model, which attempts to mimic a GaN nanowire. Conductive properties of this model are investigated by our novel quantity, a local conductive density tensor. For the analysis of nano-materials, such as nanowires, this local quantity is very useful. To use this, electronic current is required to be represented as quantum states. We have developed our new code for this purpose. Conductive states are included as plain waves in the code. We confirm that the local conductivity realizes some reasonable conductive properties, e.g., the conductive path between the nearest atoms. In addition, the rotational behavior of conductivity is found, which appears as complex eigenvalues of a conductivity tensor. This behavior can only be studied by the analysis using the tensor.
