Correlation between barrier heights and ideality factors of Cd/n-Si and Cd/p-Si Schottky barrier diodes

Our goal is to experimentally investigate whether or not the effective Schottky barrier heights (SBHs) and ideality factors obtained from the current – voltage (I –V) and capacitance – voltage (C – V) characteristics differ from diode to diode even if the samples were identically prepared. For this purpose, we prepared Cd/n-Si (33 dots) and Cd/p-Si (15 dots) diodes. The SBH for the Cd/n-Si diodes ranged from 0.701 to 0.605 eV, and ideality factor n from 1.913 to 1.213. Fb value for the Cd/p-Si diodes ranged from 0.688 to 0.730 eV, and ideality factor n value from 1.473 to 1.040. The experimental SBH distributions obtained from the C 22 –V and I–V characteristics were fitted by a Gaussian function and their mean SBH values were calculated. Furthermore, the laterally homogeneous barrier heights were also computed from the extrapolation of the linear plot of

Analysing Enhancement of Electricity Generating Capacity with Solar Tracking System of the Most Sunning Region of Turkey

Despite the increasingly widespread production of electricity from solar energy and despite Turkey is in the sun belt, Turkey cannot used its potential sufficiently effective and widely. Especially, this situation is of more importance for the Southeastern Anatolia Region Turkeys most sunning area. In this study, among renewable energy resources the generation of electricity from solar energy in terms of both its current potential and production technologies and the solar energy potential of Southeastern Anatolia Region provinces and the degree and method of using this potential to generate electricity have been investigated. Suggestions have been made to benefit from the solar energy in a way of effective and widespread for Southeastern Anatolia Region. Also, a suggestion for convenient place which is 130 m 2 and was formed by Karacadag volcanic eruption and is not used for agriculture and rocky area has been made.
