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.

Introduction Increased demands for precision components made of brittle materials such as optical glasses and advanced ceramics are such that conventional grinding and polishing techniques can no longer meet the requirements of today’s precision engineering.
Diamond cutting is a promising alternative to grinding and polishing techniques for fabricating high quality surfaces on brittle materials as a well-defined single point tool is more predictable than a multi-point grinding wheel [1-3].

However, components made with these materials usually work under harsh conditions such as high-temperature, high-speed and high-pressure, so the surface quality requires high performance.
AE is commonly defined as transient elastic waves within a material caused by the release of localized stress energy.

Fused Deposition Modelling (FDM) of thermoplastic materials is generally a well-known technology among all additive manufacturing (AM) technologies and therefore, it is essential to investigate the mechanical properties of such FDM processed materials.
Among these, Cube 3D Printers are new and small machines for printing acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) materials [2].
