The present invention discloses a dielectric structure, a transistor and a manufacturing method thereof with praseodymium oxide. The transistor with praseodymium oxide comprises at least a III-V substrate, a gate dielectric layer and a gate. The gate dielectric layer is disposed on the III-V substrate, and the gate is disposed on the gate dielectric layer, and the gate dielectric layer is praseodymium oxide (PrxOy), which has a high dielectric constant and a high band gap. By using the praseodymium oxide (Pr6O11) as the material of the gate dielectric layer in the present invention, the leakage current could be inhibited, and the equivalent oxide thickness (EOT) of the device with the III-V substrate could be further lowered.

A sun tracking mechanism is provided for solar power generation, including a power unit, a linear actuator and at least two universal joints. The sun tracking mechanism outputs an angle of high precision by two axial directions provided from the universal joints, the power unit and the linear actuator. A solar power module disposed on the sun tracking mechanism generates electricity in the best light incident angle. In addition, the linear actuator provides an auxiliary supporting force to improve the wind-resistant capability.
