Summary: RF magnetron sputtering was used to grow silicon nitride thin film on GaAs substrate to form metal-oxide-semiconductor capacitor. The complex dielectric permittivity, complex electric modulus, and complex electrical conductivity of the prepared capacitor were studied in detail. The dielectric constant and loss decreased with increasing frequency, while increased with temperature, and the ac conductivity increased with both temperature and frequency. Activation energy was determined by Arrhenius equation, and the frequency dependence of ac conductivity was analyzed, providing the value of the frequency exponent.

Summary: Ammonium dihydrogen phosphate (ADP) crystals were grown using a slow evaporation technique, and the influence of shockwaves on grain growth, defects, and electrical properties of ADP crystals was comprehensively studied. The results indicated that shockwave treatment improved dielectric properties and reduced grain resistance, with both pristine and shockwave-treated crystals showing a non-Debye-type relaxation process. The activation energies of the crystals obtained from different formulations were also in good agreement, suggesting a consistent response to the shockwave treatment.
