1.4.3 The Si/SiO2 /Si Varactor By bonding two thin silicon wafers, each with a thin layer of silicon dioxide, it is possible to form a structure similar to HBV diodes from III-V compounds. The SiO2 layer blocks the conduction current very efficiently, but the drawback is the relatively low mobility of silicon.
Boron - Wikipedia
Boron carbide and cubic boron nitride powders are widely used as abrasives. Boron nitride is a material isoelectronic to carbon . Similar to carbon, it has both hexagonal (soft graphite-like h-BN) and cubic (hard, diamond-like c-BN) forms. h-BN is used as a high temperature component and lubricant. c-BN, also known under commercial name borazon ,  is a superior abrasive.

Materials Science and Engineering: Ceramics | …
Ceramic materials are used in electronics because, depending on their composition, they may be semiconducting, superconducting, ferroelectric, or an insulator. Ceramics are also used to make objects as diverse as spark plugs, fiber optics, artificial joints, space shuttle tiles, cooktops, race car brakes, micropositioners, chemical sensors, self lubriing bearings, body armor, and skis.

Microscale Characterization of Mechanical Properties | …
INTRODUCTION Efforts to characterize the small-scale and scale-specific mechanical properties of materials are driven by (a) the need to reliably predict the performance of microelectromechancial systems (MEMS) and other microscale devices and (b) a desire to develop detailed and accurate hierarchical models of the mechanical behavior of complex, multicomponent structural materials.
Silicon carbide having high hardness and strength showed strong resistance to granule collisions during the FBR process using a lab-scale reactor. And it also showed quite good compatibility with the typical FBR processes of MS and TCS resources. 10.5695
