2-25.FWHM
Full width at half maximum (FWHM) is an expression of the extent of a function, given by the difference between the two extreme values of the independent variable at which the dependent variable is equal to half of its maximum value.

Most SiC electronic devices are not fabricated directly in sublimation-grown wafers, but are instead fabricated in much higher quality epitaxial SiC layers that are grown on top of the initial sublimation grown wafer. Well-grown SiC epilayers have superior electrical properties and are more controllable [...]

5-5 SiC Device Fundamentals
To minimize the development and production costs of SiC electronics, it is important that SiC device fabrication takes advantage of existing silicon and GaAs wafer processing infrastructure as much as possible. As will be discussed in this section, most of the [...]

5-6-4-1-2 Bipolar and Hybrid Power Rectifiers
For higher voltage applications, bipolar minority carrier charge injection (i.e., conductivity modulation) should enable SiC pn diodes to carry higher current densities than unipolar Schottky diodes whose drift regions conduct solely using dopant-atom majority carriers . Consistent with silicon [...]

1-1.lattice parameter
The lattice constant, or lattice parameter, refers to the constant distance between unit cells in a crystal lattice. Lattices in three dimensions generally have three lattice constants, referred to as a, b, and c. However, in the special case of cubic crystal structures, [...]
