Self-consistent analysis of the contact phenomena in low-mobility semiconductors
نویسندگان
چکیده
Self-consistent solution of charge injection and charge transport in low mobility light emitting diodes ~LEDs! is reported. We show that an explicit description of the contact region under the same premise as the transport equations is needed to accurately evaluate the current–voltage characteristics of polymer or small-molecule based LEDs. The results are compared to widely used models, which treat the contact region in an implicit manner. © 2003 American Institute of Physics. @DOI: 10.1063/1.1539534#

Field Dependent Charge Carrier Transport for Organic Semiconductors at the Time of Flight Configuration
In this paper, we used the time-of-flight (TOF) of a charge packet, that injected by a voltage pulse to calculate the drift velocity and mobility of holes in organic semiconducting polymers. The technique consists in applying a voltage to the anode and calculating the time delay in the appearance of the injected carriers at the other contact. The method is a simple way to determine the charge t...
متن کاملScattering mechanism of nonmagnetic phase on nano diluted magnetic semiconductors (DMS)
This paper shows the scattering mechanism at diluted magneticsemiconductors. The doped magnetic atom produces a scattering potential due to becoupled of itinerant carrier spin of host material with magnetic momentum of the dopedmagnetic atom. Formulas of scattering event were rewritten by the plane waveexpansion and then the electron mobility of DMS was calculated. Calculations showKondo effect...

Immiscible metals due to their inherent specs are insoluble over the steady state. Developing an innovative approach to this issue would be fascinating and challenge the overriding rules. Herein, we proffer the principles of synthesis of Cu-Nb nanocomposites using electrochemical deoxidation route. This method consists of the cathodic electrolysis of the nanoparticles Cu-Nb2O5 through the...
متن کاملCharge carrier mobility in thin films of organic semiconductors by the gated van der Pauw method
Thin film transistors based on high-mobility organic semiconductors are prone to contact problems that complicate the interpretation of their electrical characteristics and the extraction of important material parameters such as the charge carrier mobility. Here we report on the gated van der Pauw method for the simple and accurate determination of the electrical characteristics of thin semicon...
متن کاملGeneralized Einstein relation for disordered semiconductors—implications for device performance
The ratio between mobility and diffusion parameters is derived for a Gaussian-like density of states. This steady-state analysis is expected to be applicable to a wide range of organic materials ~polymers or small molecules! as it relies on the existence of quasiequilibrium only. Our analysis shows that there is an inherent dependence of the transport in trap-free disordered organic materials o...
