Abstract :
Synthesis of SnS/TiO2 nanocomposite was done by thermal evaporation method. The field emission characteristics have been investigated at room temperature. The field emission current density versus applied field (J-E) and emission current versus time (I-t) characteristics were measured in a planer diode configuration at the base pressure of 1 × 10-8 mbar. Turn-on field defined for the emission current density of 0.1μA/cm2 has been found to be 1.2 V/μm and upon the application of high applied electric field of 4.6 V/μm maximum current density of 0.454 mA/cm2 has been achieved. The I-t measurement has been studied at the preset of 1 μA emission current for the duration of 3 hr. Overall nature of emission current has been seen to stable for duration of measurement.
