Question

the height of the barrier determines by using
a) normal energy
b) activated complex
c) reactants
d) threadshold energy

​

Answer 1

Answer:

The barrier height ϕB, defined in figure 1, is calculated from charge neutrality and charge distribution between the metal (surface charge density Qm), the oxide (fixed charge q Nf), the interface-trapped states (Qit) and the semiconductor (charge in the depletion region Qs.

Answer 2

The barrier height ϕB, defined in figure 1, is calculated from charge neutrality and charge distribution between the metal (surface charge density Qm), the oxide (fixed charge q Nf), the interface-trapped states (Qit) and the semiconductor (charge in the depletion region Qs).
