dc.description.abstract | The current-voltage (I-V) characteristics of Ag Schottky contacts on a Bridgman-Stockbarger grown p-type SnSe layered semiconducting material have been measured over the temperature range of 80-350 K. Their analysis based on the thermionic emission (TE) theory has revealed an abnormal decrease of zero-bias barrier height and increase of ideality factor at lower temperatures. This behaviour has been interpreted on the basis of the assumption of a Gaussian distribution of barrier heights due to barrier height inhomogeneities that prevail at the interface. The inhomogeneities are considered to have Gaussian distribution with a mean barrier height of (Phi) over bar (b0) 0.610 eV and standard deviation of sigma(s0) = 0.075 V at zero-bias. Furthermore, the mean barrier height and the Richardson constant values were obtained by means of the modified Richardson plot, In(I-0/T-2) - (q(2)sigma(s0)(2)/2k(2)T(2)) versus 1000/T, as 0.603 eV and 7.72 A K-2 cm(-2) respectively, of which latter is close to its theoretical value of 18 A K-2 cm(-2) used for the determination of the zero-bias barrier height. Hence, it has been concluded that the temperature dependence of the I-V characteristics of the Schottky barrier on p-type SnSe can be successfully explained on the basis of TE mechanism with Gaussian distribution of the barrier heights. | en_US |
