Abstract :The Al/Mg2Si/p-Si Schottky diode was fabricated using spin coating. The real insert ignore into journalissuearticles values(ε′); and imaginary insert ignore into journalissuearticles values(ε′′); components of complex dielectric insert ignore into journalissuearticles values(ε*);, the real insert ignore into journalissuearticles values(M′); and imaginary insert ignore into journalissuearticles values(M′′); components of complex electric modulus insert ignore into journalissuearticles values(M*); and AC electrical conductivity insert ignore into journalissuearticles values(σ AC ); of the fabricated Al/Mg2 Si/p-Si Schottky diode insert ignore into journalissuearticles values(SD); were examined by using the impedance spectroscopy insert ignore into journalissuearticles values(IS); measurements in a wide frequency range of 1 kHz-1 MHz. The ε ′ and ε ′ ′ were obtained using the value of measured capacitance and conductance while the values of dielectric loss tangent insert ignore into journalissuearticles values(tanδ, M′, M′′ and σAC were obtained using the value of ε′ and ε′′. While the values of ε′, ε′′ and tanδ are almost independent of the frequency in the inversion and accumulation region, their value changes with the frequency, especially in the depletion region. The σAC was examined depending on the frequency and it was seen that its value increased with increasing frequency especially in depletion and accumulation region. The experimental results showed that the Mg2 Si can be used instead of conventionally used dielectric materials insert ignore into journalissuearticles values(SnO2 , SiO2 );.
