Curent-Voltage (I-V) properties of Au/6H-SiC/Au Schottky diodes are investigated and results are analised dependent on temperature at 80-400 K range. Fundamental parameters such as ideality factors (n), barrier heights (Phi(bo)), saturation currents (I-o) are calculated for this diode. Also, series resistance (R-s) is calculated with different methods. Richardson curves are plotted for this structure and Richardson constant (A*) is calculated. Results are compared with literature. Gaussian distribution is examined by using barrier inhomogeneity. Parameters belonging to Gaussian disribution are calculated and results are compared with previous studies done by different authors.
