      The book provides an overview of the author's work devoted to experimental study of hopping conductivity, which includes substantial contributions, such as solving the problem of critical indices of the metal-insulator transition in doped semiconductors, investigation of transitions from different kinds of hopping conductivity, development of the "hopping spectroscopy" method that allows to Brand: World Scientific Publishing Company. The electrical transport properties of boron doped graphitelike amorphous carbon films have been studied. Variable range hopping (VRH) conduction is found to be the conduction mechanism in these carbon films. The conduction in high temperature regime follows the Mott VRH [J. Non-Cryst. Solids 1, 1 ()], whereas a crossover from the Mott [Electronic Process in Non-crystalline Materials Cited by:

      Ion conduction in solids has been known for more than a century [1]. The first electrical conductive solid was discovered by Michael Faraday who, in , reported that the electrical conductivity of Ag 2 S was largely increased with increase in temperature [2]. Additionally, he discovered similar behavior in several other inorganic solids such as PbF 2, in [3]. Conduction (TAC) between and K, Nearest-Neighbor Hopping (NNH) conduction between and K, and Variable Range Hopping (VRH) conduction below 58K, with a crossover from the 3D-Mott-VRH to the 3D-Efros-Shklovskii-VRH at 16K. We claim that this sequence reveal the three-dimensional nature of the electrical transport in the SnOCited by:

We present a quantitative analysis of ac electrical conductivity and dielectric constant measurements that were performed on boron carbide samples. This material is crystalline but disordered on the atomic scale because of the existence of a large stoichiometry range from B{sub 9}C to B{sub 4}C. The.

The average of hopping distance, r ¯, which optimizes the product of the two factors, turns out to be r ¯ Hopping conduction in solids book T − 1 / 4, which leads to the hopping conductivity in Equation (74). Since the optimized hopping distance varies with T, as illustrated by process (ii) in Figure 22(b), this mechanism of hopping conduction is known as the VRH.

Section studies the effect of a magnetic field on hopping conduction in the VRH regime. Section describes a peculiar size effect which occurs in thin films of amorphous semiconductors with VRH conduction, and arises due to the finite volume accessible to by: Hopping Transport in Solids.

After a description of the states with the help of localization radius and the general expression for the transition probability between two states — the hopping conductivity theory — is presented. The theory is based on Abrahams-Miller network of random resistances modelling an insulator and the percolation theory.

The conduction mechanisms in dielectric films are crucial to the successful applications of dielectric materials.

There are two types of conduction mechanisms in dielectric films, that is, electrode-limited conduction mechanism and bulk-limited conduction mechanism.

Such processes do not occur in conventional electronic transport in solids, since localized states are not compatible with the translational symmetry of crystals. Organic semiconductors are solids whose building blocks are pi-bonded molecules or polymers made up by carbon and hydrogen atoms and – at times – heteroatoms such as nitrogen, sulfur and exist in form of molecular crystals or amorphous thin general, they are electrical insulators, but become semiconducting when charges are either injected from appropriate electrodes.

The electrons and holes localized in impurities or defects do not participate in the conduction (they can participate in hopping conduction but its mobility is comparatively much lower).

The transition of an electron or a hole from a localized state to a delocalized one or the creation of an electronhole pair is called generation, the inverse.

The field of charge conduction in disordered materials is a rapidly evolving area owing to current and potential applications of these materials in various electronic devices This text aims to cover conduction in disordered solids from fundamental physical principles and theories, through practical material development with an emphasis on.

Throughout the book the term ``hopping'' is defined as the inelastic tunneling transfer of an electron between two localized electronic states centered at different locations.

Such processes do not occur in conventional. The dc and ac conductivities of Mn-doped ZnO were investigated at temperatures from 10 to K. The temperature dependence of the dc conductivity from 10 to K shows an abrupt change at ∼18 K, manifesting a much lower activation energy for conduction below 18 by:
