Title:
ELECTROLUMINESCENCE SAMPLE ANALYSIS APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/139021
Kind Code:
A2
Abstract:
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 variator 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.
