2017/11/1The power density was one of the most important parameters during laser irradiation on the aromatic PI film. The effect of power density on the graphene formation was investigated for optimization by changing the power density from 3.95 to 9.63 kw/cm 2 at a scanning speed of 0.4 mm/s, as a minimum power density was needed to initiate the graphitization process and high power density could

Status of silicon carbide (SiC) as a wide

Silicon carbide (SiC), a material long known with potential for high-temperature, high-power, high-frequency, and radiation hardened applications, has emerged as the most mature of the wide-bandgap (2.0 eV ≲ E g ≲ 7.0 eV) semiconductors since the release of commercial 6H SiC bulk substrates in 1991 and 4H SiC substrates in 1994. . Following a brief introduction to SiC material properties

Thermal Expansion Coefficients of 6H Silicon Carbide

The values for the thermal expansion coefficients along the a- and c-direction, α11 and α33, are in the range of 310-6 K-1 for 300 K and 610-6 K-1 for 1550 K. At high temperatures the coefficients for aluminum doped samples are approximately 0.510-6 K-1 lower than for the nitrogen doped crystal. α11 and α33 appear to be isotropic.
