Summary: The effect of different concentrations of zinc oxide on the dielectric properties of composite films was studied. It was found that increasing the zinc oxide content significantly increased the dielectric constant, AC conductivity, and loss tangent. A direct correlation between the dielectric parameter and the mean relaxation time of polymer chain segmental dynamics was observed, suggesting that the dielectric properties of these materials can be tailored by varying the amount of metal oxide filler for use in microelectronics.

Summary: The demand for high-speed communication at high frequency has led to the development of low-dielectric polymer films. Aromatic polyimide (PI) is commonly used in flexible circuit boards due to its excellent properties, but its dielectric constant is relatively high for high-frequency communication. To address this, a hyper-crosslinked polymer (HCP) was synthesized and blended with PI to form all-organic HCP/PI composite films. The porous structure of HCP helps to reduce the dielectric constant of the PI matrix. By adjusting the HCP content, the dielectric constant of the composite films can be effectively lowered in the desired frequency range. This method is simple and can be applied to other organic component-filled PI systems.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
