Diffusion, Static Charges, and the Conduction of Electricity in Nonmetallic Solids by a Single Charge Carrier. I. Electric Charges in Plastics and Insulating Materials

Abstract

The dynamic equilibrium of space charge in insulators such as ceramics, molecular crystals, or high polymers, is considered from the thermodynamic point of view with quantum-mechanical boundary conditions. The treatment constitutes the opposite extreme from the usual ohmic; conduction equations; in the first paper, only the zero-current equilibrium of charge is considered. Applications are"made to the observed charging of high polymers during molding... * Initially

Charge Distribution and Contact Resistance Model for Coplanar Organic Field-Effect Transistors

“…Charge distribution inside the organic semiconductor of a coplanar-type OFET. The analytical curves are obtained by (15), (17), (23), and (27). Note that the device simulator brings very close results.…”

“…Even though the Mott-Gurney model provides meaningful insight into the charge distribution, its usage should be limited to very thick organic crystals and this model cannot be safely applied to thin organic films. Skinner stepped forward and developed more general solutions to (5) [15]. It means that one can challenge the 'finite' junction without forcing g to zero.…”

“…In other words, F (0) is negative and F (y) approaches zero from y = 0 to y = d. At y = d, F becomes zero by the boundary condition and dF/dy remains positive. Therefore, the right-hand term in (5) is negative and the corresponding solution is the trigonometric function in [15], which can be written in the form;…”

“…We can infer from (15) and (17) that E b and V G are the principal parameters for the source and channel distribution of charges. The results presented in Fig.…”

Modeling electrical characteristics of laser tuned silicon microdevices

“…The J-V relation of a n+ υ n+ structure has been extensively studied in the past [7][8][9][10][11][12]. Single carrier transport can be described by the drift-diffusion equation where the diffusion current is ignored and by a field dependent mobility expression based on the Canali et al model [13].…”
