  The charge carrier transport in metal phthallocyanine based disordered thin
films has been investigated. Charge carrier mobility in these disordered thin
films strongly depends on the electric field and temperature due to hopping
conduction. The applicability of two different Gaussian disorder models has
been compared and evaluated for charge carrier transport using simple
experimental results and based on our extensive analysis, it has been found
that spatial and energetic correlation is important in explaining the
electrical transport in these organic semiconductors.
