Photoconductivity is the incremental change in the electrical conductivity of a semiconductor
or insulator upon illumination. The behavior of photoconductivity with photon energy, light …

The steady-state photocarrier grating technique allows the determination of the ambipolar
diffusion length in low-mobility semiconductors and provides access to the minority-carrier …

In this paper we apply various photoconductivity techniques to study different types of
semiconductors. These methods are the modulated photocurrent, the steady-state …

In this paper, we show that the combination of different characterization techniques based
on the photoconductivity of hydrogenated amorphous silicon can be a tool to investigate on …

We report on a theoretical model to describe the non-steady-state photoelectromotive-force
(photo-EMF) effect in organic photoconductors. Unlike the conventional theory of the photo …

In this chapter, we detail photoconductivity techniques based on the illumination of a sample
in a coplanar electrode configuration with a light intensity periodically modulated in space …

In this paper we examine and cross-check the information that can be extracted from
different photoconductivity experiments. First, taking account of localized states in the band …

We propose to use steady state measurements and a teaching-learning-based optimization
(TLBO) algorithm to get the complete set of material transport parameters of disordered …

We present a method to obtain the density of states of photoconductive semiconductors
based on the light-intensity dependence of the steady-state photoconductivity. A simple …

Thin film semiconductors are more and more the major components of solar devices.
Nevertheless, these materials are still the subjects of intense research to improve their …
