Silicon carbide is a semiconductor that is now widely used in a variety of micro-electromechanical systems, light-emitting diodes and high-power electronics. Its technological appeal stems from the fact that it is amenable to mature, robust nanofabriion methodologies and possesses both a high Young’s modulus and excellent thermal conductivity. To many, silicon carbide is a material that

Effect of Neutron Irradiation on SiC Etching in KOH Melt | …

Abstract: The effect of reactor neutron irradiation on the SiC crystals etching rate in KOH melt has been investigated. It is shown that at high doses of irradiation (10 19 - 10 21 neutrons/cm 2) the SiC etching rate sharply increases, especially in the [0001] Si direction, leading to essential reduction of orientation anisotropy of polar {0001} faces etching.

Superradiant terahertz lasing with graphene metamaterials

Graphene microcavities were confined between metal grating contacts on the flat surface of a dielectric substrate of silicon (silicon carbide can also be used). An external THz wave was incident upon the planar array of graphene microcavities normal to its plane, with polarization of the electric field across the metal grating contacts.
