is the diode's builtāin voltage in the forward bias region. It is a function of temperature and doping and decreases with increasing temperature and doping concentration in N type semiconductor. The forward voltage drop of Schottky barrier diode is low compared to normal pn junction diode it is between 0.3 volts and 0.5 volts. In a Schottky barrier diode current conduction is through majority carriers which are electrons in N type semiconductor. The current in Schottky barrier diode current is
