Web3.1 K Value The first requirement for the candidate oxide is that K should be over 10, preferably 25-30.From the table and figure it can be seen that the value of K vary inversely with the band gap. So we must accept a relatively low K value. There are oxides with very large K values such as SrTiO 3 but this has low band gap i.e 3.2eV. In WebAl2O3 has a limited k-value of around 8 but a large bandgap of 8.8 eV, a small electron affinity of 1.3 eV giving a barrier height of 3.7 eV. HfO2 combines the benefits of both Al2O3 and Ta2O5 in offering a high dielectric constant of 25, moderate bandgap (6.0 eV) and electron affinity (2.5) with reasonable barrier height (2.5 eV). how many kg is 144 pounds https://aksendustriyel.com
