Summary

This chapter discusses the process for manufacturing high quality organic light-emitting diode (OLED) devices. Basic material properties are divided into four types: Hole Injection Layer (HIL); Hole Transportation Material (HTM); Emission Layer (EML); Electron Injection Layer (EIL). The evaporation process involves conversion of a solid or a liquid to the vapor state by heating the material in an evaporation source. In electron beam evaporation, an accelerated electron beam is emitted toward the target material to evaporate it. In thickness measurement using a quartz oscillator, the oscillation frequency of the quartz is reduced because of the effective change in mass due to the film formation. The cyclic voltammetry (CV) method, which measures potential and electric current simultaneously, is useful for analyzing electrochemical reactions by determining parameters such as electron transfer speed, reversibility, and chemical dissociation during reaction.
