Abstract
Official abstract text for this publication.
Provided is an apparatus for analyzing an electroluminescence sample, which comprises: a pulse generator for applying a pulse driving signal to the electroluminescence sample; an electroluminescence (EL) detector for receiving electroluminescence which is emitted from the electroluminescence sample according to the application of the pulse driving signal, thereby acquiring a light-receiving signal; a temperature controller for varying the temperature of the electroluminescence sample; and an electroluminescence transient spectroscopy (ELTS) analysis unit for analyzing a change in a time division section of the light-receiving signal delayed depending on a change of the temperature of the electroluminescence sample, and acquiring information on a defect-type charge trap which exists in the electroluminescence sample.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for analysis of an electroluminescence sample comprising: a pulse generator configured for applying a pulse driving signal to the electroluminescence sample; an electroluminescence (EL) detector configured for acquiring a light-receiving signal by receiving electroluminescence emitted from the electroluminescence sample as a result of application of the pulse driving signal, wherein the light-receiving signal obtained by the EL detector is one…
