Abstract
It was confirmed that current flowing in thin films below nm increases conductivity in diffusion currents by holes rather than electric currents by electrons. ZTO thin film, which was heat treated at $150^{\circ}C$, increased electron concentration, and thus increased capacitances. However, it was found that low current movement would be difficult as the degree of movement was reduced. Therefore, it was found that diffusion currents were more advantageous than drift currents by electrons in order to allow low current to be produced in very thin films of nm class.
