What is the dielectric strength of silicon dioxide? How …

The dielectric strength of silicon dioxide, [math]SiO_2[/math] is about 10 MegaVolts/cm which works out to 1000 V/micrometer. Thin films are on the order of 0.1 micrometers and should therefore have a breakdown of about 100 V. This is rarely achie

On the Evaluation of Gate Dielectrics for 4H-SiC Based …

AlN and Al 2 O 3 are two promising compatible (almost similar dielectric constant with 4H-SiC) candidates as gate dielectric with 4H-SiC materials. However, lower bandgap of AlN (6.2 eV) in comparison with Al 2 O 3 (8.7 eV) or SiO 2 (8.9 eV) might be disappointing for 4H-SiC devices, but a lattice mismatch to SiC of only 1% along with almost the same thermal expansion coefficient of up to …
