Ⅰ. Need Of Alternative Energy
The need for alternative energy sources is getting urgent, hence the development of renewable energy is moving fast. Nationally and internationally various individuals and research companies are creating new and exciting energy systems. Some of these apparatus are great works and need improving for massive use. Politician's world-wide are dra

3.Result and Discussion
Fig. 1 shows the XRD patterns from the as-grown films. There is no new peak appearing when RF power of Ge is 0 W except for three peaks of ZnO (1 0 0), (0 0 2)and (0 0 4) located at 2θ = 30.888, 34.218, and 72.138, respectively. At RF power 100 W, these three peaks shift toward larger angle apparently and their intensity has also enhanced slightly. This indicates tha
