TL;DR: In this paper, a physics-based model and an experimental method were proposed to extract the built-in potential of an organic diode and solar cell from current density-voltage characteristics.

TL;DR: In this paper, the correlation between the contact effect and hysteresis was demonstrated by comparing gold contact and silver contact devices with having low and high contact resistances respectively, and a simplistic analysis based on charge trapping in the vicinity of the source terminal was proposed to explain the scaling behavior of hystresis with channel length.

TL;DR: In this article, the operation principle of an organic metal-insulator-semiconductor (MIS) capacitor where the organic semiconductor is undoped is presented, and a physics-based model is developed to derive the charge concentration, surface potential, and the capacitance of the organic MIS capacitor.

TL;DR: In this article, the enhancement of conduction in the organic field effect transistors on light illumination is studied using phase sensitive photocurrent measurements on pentacene FET transistors, and two models are proposed on the exciton dynamics in the presence of gate induced polarons in the transistor channel.

TL;DR: In this article, the authors show that the capacitance dispersion with respect to frequency and temperature in organic MIS capacitor devices is an inherent property, which arises due to the low conductivity of the semiconductor along with Schottky type contact at semiconductor-metal junction.
