Temperature dependent electrical characteristics of an organic–inorganic heterojunction obtained from a novel organometal Mn complex

This study includes synthesizing a Mn hexaamide (MnHA) organometal compound (C 27H 21N 9O 6MnCl 2)·(1/2H 2O), fabrication of MnHA/n–Si organic–inorganic heterojunction and analysis of conduction mechanism of the device over the room temperature. After synthesizing the molecule, the structure of the compound was determined using spectroscopic methods. The Sn/MnHA/n–Si structure was constructed by forming a thin MnHA layer on n–Si inorganic semiconductor and evaporating Sn metal on organic complex. The structure has shown good rectifying behavior and obeys the thermionic emission theory. The current–voltage ( I– V) characteristics of the diode have been measured at temperatures ranging from 300 to 380 K at 10 K intervals to determine the temperature dependent electrical characteristics of the device.
