Carbon can be produced from pyrolysis and heating process of organic materials [1].
In developing and fabricating battery, carbon-based materials are still the mainstream active components for the electrode materials in batteries due to their high surface area, high electrical conductivity, and excellent chemical stability.
One of the carbon materials that is easy to synthesize is activated charcoal.

The Effect of Ternary Material (Zr, Y, and O) High-k Gate Dielectrics K.C.
Introduction High-k materials are widely discussed as the new gate insulators that are used to reduce the leakage current in metal-oxide-semiconductor field effect transistors (MOSFETs) for next generation [1].
Summary In this study, the high dielectric material, Y2O3, is used to replace the traditional dielectric material, SiO2, in MOS capacitor and Zr is doped with different stack structure for avoiding the diffusion effect of other materials.
