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(27)H(21)N(9)O(6)MnCl(2)). (1/2H(2)O), 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 380K at 10 K intervals to determine the temperature dependent electrical characteristics of the device.
