Ammonium phosphomolybdate: a material for dielectric crossover and resistive switching performance.

ABSTRACT: The yellow ammonium phosphomolybdate [(NH₄)₃PMo₁₂O₄₀] (YAPM) is a robust and elegant compound that has found innumerable field applications. Herein, we have shown that this inorganic polymer serves as a novel dielectric material and a compound for memory device fabrication. It displays changeable dielectric performance and ac conductivity under UV (∼365 nm) irradiation. Drastic lowering of the dielectric constant (ε') was observed with the increase in dielectric loss factor, which was ascertained due to electron accumulation under UV exposure producing green APM (GAPM). The contributions of the Maxwell-Wagner polarization and the dipolar relaxation are correlated with the charge transfer and dielectric contribution of the material. Interes
