What is it about?
The entropy-ruled method gives a new dimensional understanding of electron/hole dynamics in different semiconducting materials for both the cases of generate and nondegenerate with wide temperature ranges. At appropriate limits, we preserve the original Einstein relation from Navamani's D/μ ratio (or entropy-ruled diffusion-mobility relation).

Why is it important?
Significance of this paper: 1) We introduced here non-steady energy flux principle for diffusive systems 2) developed "Entropy-Ruled Method" to explore the electron hole transport in molecular solids, 3) Accordingly (using Entropy-Ruled Method), the Shockley diode equation is modified for molecular quantum devices, which is known as Navamani-Shockley diode current density equation.
Perspectives
Navamani's entropy-ruled charge transport method connects the adiabatic band and non-adiabatic hopping mechanisms. The one-to-one variation between effective entropy and chemical potential are fundamentally important for understanding the cutting-edge organic semiconductors, which is indeed ideal for next-generation semiconductor technology. The important point is here that the changes of effective entropy with respect to the chemical potential or vice versa is the key descriptor to explore both the quantum and classical features of charge and energy transport in any molecular devices.
