Self-consistent analisys of the contact phenomena in low-mobility semiconductors

TL;DR

This paper presents a self-consistent approach to analyze contact phenomena in low-mobility semiconductors, emphasizing the importance of explicit contact region modeling for accurate current-voltage predictions in LEDs.

Contribution

It introduces a self-consistent method that explicitly models contact regions, improving upon traditional implicit contact models for low-mobility semiconductor devices.

Findings

Explicit contact modeling improves accuracy of I-V characteristics

Self-consistent solution captures contact effects more reliably

Comparison shows traditional models are less accurate

Abstract

Self-consistent solution of charge injection and transport in low mobility LEDs is reported . We show that explicit description of the contact region under the same premise as transport equation is needed to accurately evaluate the current-voltage characteristics of polymer or small-molecule based LEDs . The result is compared to widely used models, which treat the contact region in implicit manner .
