Abstract
The Al/tetraamide-I/p-Si Schottky barrier diode (SBD) has been prepared by adding a solution of a novel nonpolymeric organic compound chiral macrocylic tetraamide-I in chloroform on top of a p-Si substrate and then evaporating the solvent. It has been seen that the forward-bias current-voltage (I-V) characteristics of Al/tetraamide-I/p-Si SBD with a barrier height value of 0.75Â eV and an ideality factor value of 1.77 showed rectifying behaviour. The energy distribution of the interface state density determined from I-V characteristics increases exponentially with bias from 5.81Â ÃÂ 1012Â cmâ2Â eVâ1 at (0.59-Ev)Â eV to 1.02Â ÃÂ 1013Â cmâ2Â eVâ1 at (0.40-Ev)Â eV. It has showed that space charge limited current (SCLC) and trap charge limited current (TCLC) are the dominant transport mechanisms at large forward-bias voltages.
