A review on electrical transport properties of thin film Schottky diode

Abstract

The article outlines an inclusive list of thin film Schottky diodes (TFSD) references. The review audits the fabrication and characterization of the TF metal-semiconductor (MS) diode, a TFSD. The work functions of metal (ϕ m) and semiconducting material (ϕs ) determines whether the established MS contact is ohmic or rectifying. Current-voltage (I – V) and capacitance-voltage (C – V) characterizations are essential electrical transport measures of TFSDs. The I – V and C – V outcomes are conferred, and archetypal results are parroted. The TFSD device is emblematic of a heterojunction diode (HJD). The rectification ratio (RR), saturation current (I0), ideality factor (n), Schottky barrier height (ϕB), and carrier concentration may all be calculated using I – V and C – V data. Thermionic emission (TE) and/or space charge limited conduction mechanisms (SCLC) may conduct electricity in TFSDs. Anderson’s model can theoretically be used to construct a TFSD energy band diagram.
