Herein, we focus on the principles of photoconduction in random semiconductors—the key processes being optical generation of charge carriers and their subsequent transport. This is not an overview of the current work in this area, but rather a highlight of elementary processes, their involvement in modern devices and a summary of recent developments and achievements. Experimental results and models are discussed briefly to visualize the mechanism of optical charge generation in pure and doped organic solids. We show current limits of models based on the Onsager theory of charge generation. After the introduction of experimental techniques to characterize charge transport, the hopping concept for transport in organic semiconductors is outlined. The peculiarities of the transport of excitons and charges in disorderd organic semiconductors are highlighted. Finally, a short discussion of ultrafast transport and single chain transport completes the review.

“…The good air stability was also observed, which indicates that cyano substituent is another efficient way to lower the LUMO energy level and achieve stable n-type materials. Later on, the core-expand NDI bearing two 2-(1,3-dithiol-2-ylidene)malonitrile moieties at the core (14) needs to be mentioned due to its good solution processability and good air stability [52].…”

Organic field-effect transistors have received much attention in the area of low cost, large area, flexible, and printable electronic devices. Lots of efforts have been devoted to achieve comparable device performance with high charge carrier mobility and good air stability. Meanwhile, in order to reduce the fabrication costs, simple fabrication conditions such as the printing techniques have been frequently used. Apart from device optimization, developing novel organic semiconductor materials and using thin-film alignment techniques are other ways to achieve high-performance devices and functional device applications. It is expected that by combining proper organic semiconductor materials and appropriate fabrication techniques, high-performance devices for various applications could be obtained. In this chapter, the organic field-effect transistor in terms of device physics, organic materials, device process, and various thin-film alignment techniques will be discussed.

“…The major trait to characterize charge transport is the charge carrier mobility. Charge carrier mobility could be determined experimentally through various techniques, [4,5] such as Time of Flight (TOF), [6,7] Field-Effect Transistor (FET) Configuration, [8,9] Diode Configuration, [10] and PulseRadiolysis Time-Resolved Microwave Conductivity (PR-TRMC), [11] as well as Carrier Extraction by Linearly Increasing Voltage (CELIV). [12] Meanwhile, theoretical modeling has becoming one of the most important tools to predict the charge mobility of organic semiconducting material with the rapid progress of theoretical methodology and computer technology.…”

Theoretical Study of Electronic Structures and Charge Transport Properties of 9,10‐Bis((E)‐2‐(pyrid‐n‐yl) vinyl) (n=2,3,4) Anthracene

Charge carrier mobility is one of the most significant properties for organic semiconductors. In this work, the electronic structures and charge transport properties of 9,10-bis((E)-2-(pyrid-n-yl)vinyl) (n＝2, 3, 4) anthracene (BP2VA, BP3VA and BP4VA) were investigated via the analysis of the molecular geometry, the reorganization energy, the frontier orbital and density of state, as well as the electronic coupling and the charge mobility. The results indicated that the linkage between 9,10-divinyl anthracene unit and pyridine (ortho-, meta-and para-) influenced not only the intra-molecular conformation (i.e., the reorganization energies), but also the intermolecular interaction (i.e., transfer integrals), and finally the charge mobility of the molecules. It is also found that: (1) The calculated charge mobilties of holes are dozens of times higher than those of electrons for the three molecules. (2) The charge mobilities of hole and electron of the three molecules display the trend: μ BP4VA ＞μ BP2VA ＞μ BP3VA , and the hole mobility of BP4VA is as high as ~1 cm 2 /(V•s).
