Abstract:
ZTO was prepared on SiOC/ITO glass and the electrical characteristics were analyzed in accordance with the annealing temperature to research the temperature dependence and an amorphous structure. SiOC annealed at 150 °C as a gate insulator became an amorphous structure. The ZTO annealed at 150 °C had the capacitance without any variation. However, the capacitance of ZTO on SiOC annealed at 150 °C was increased due to the reduction of energy loss. ZTO/SiOC transistor was observed the ambipolar transfer characteristics with high stability and mobility in accordance with the decrement of drain voltages as a result of tunneling effect. Therefore it was obtained that the SiOC annealed at 150 °C means the highest Schottky barrier (SB) at the interface of ZTO/SiOC as the optimization parameter.

Temperature Dependence on Reaction Rate
Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical bonds. This premise is the basis for a theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates.
The collision theory is based on the postulates that (i) the reaction rate is proportional to the rate of reactant collisions, (ii) the reacting species collide in an orientation allowing contact between...

Semiconductors
Metals such as copper (Cu), zinc (Zn), or lead (Pb) have low resistivity and feature conduction bands that are either not fully occupied or overlap with the valence band, making a bandgap non-existent. This allows electrons in the highest energy levels of the valence band to easily transition to the conduction band upon gaining...
