IN an earlier paper1 experiments were described which demonstrated hole injection from unexcited and optically excited electrode layers into an adjacent anthracene crystal, resulting in a large increase in the current passing through the bulk of the crystal. In the present communication, the interaction between an optically excited anthracene crystal and its adjacent electrode is reported. 

Bulk Conductivity in Organic Crystals

ONE of the basic problems in the study of bulk conductivity phenomena (dark- and photo-conductivity) in organic crystals is the apparent energy deficit in the difference between the ionization energy

Pentacene Thin‐Film Transistors Encapsulated by a Thin Alkane Layer Operated in an Aqueous Ionic Environment

The encapsulation of pentacene thin-film transistors (TFTs) by a 50 nm thick layer of a long chain alkane (C₄₄H₉₀) enables the operation in an aqueous solution of 1 mM NaCl. It is the first time that

Electron Injection into Quinone Crystals

Photostimulated electron injection from an ethanol or water electrode into single crystals of tetrahalo‐substituted p‐benzoquinones was observed. The electron transfer processes involve the excited

On the conductivity of some organic dyes

The type of I–V characteristics can serve for the determination of the type of contacts as well as fordetecting an ion component in the conductivity. The dyes investigated by us, conventionally

Prospects of the Practical Application of Organic Semiconductors

At the present time, hundreds of new organic semiconducting materials have been obtained [1–3]. In this chapter we shall consider those characteristics of these materials that can be used in various

Charge Injection into Organic Crystals: Influence of Electrodes on Dark‐ and Photoconductivity

Studies have been made of dark and photoconductivity in thin anthracene single crystals using a Ce4+ solution as one electrode and a 1MNaCl solution as the other electrode. It was found that the Ce4+

The Photo-induced Electron Transfer Reactions between Crystals of Aromatic Hydrocarbons and Quinones

The photo-induced electron transfer reactions between crystals of aromatic hydrocarbons and several quinones were studied by measuring the increase of the photocurrent in the crystals due to the

The Surface of Organic Semiconductors

There is no doubt that the surface properties of organic semiconductors are extremely important both for understanding the processes taking place at the boundary of separation of two phases and for

Preparation of Thin Anthracene Single Crystals

Anthracene single crystals ranging in thickness from 4 to 80 μ and from 0.5 to 2 cm2 in area have been prepared by crystallization from a selected solution system. The method is general and employs a
