Question

The height of the barrier determines by using​
a) Normal energy
b) Activation energy
c) Complex energy
d) Threshold energy



It is one or more than answer type question
​

Answer 1

Explanation:

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

Answer:

B,D

Explanation:

TThe 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 semiconductorhe activation energy for the forward reaction is the amount of free energy that must be added to go from the energy level of the reactants to the energy level of the transition state.
