We learnt that the distribution of the states is a very important property of the organic semiconductor which is defined as Tc.
Tc is given as:
Ideality factor γ is also a very important parameter in diodes which attributed to the interface properties between the metal and semiconductor.
The ideality factor is given as:
Another essential parameter in disordered organic semiconductor is the Meyer- Neldel Energy (discussed in earlier lecture) which is given as:
T0 defines the distribution of the carriers and T is equal to room temperature which is 300K. As calculated before, To can be the values shown below,
Therefore, Tc, γand MNE is calculated:
Therefore, Tc, γand MNE is calculated:
