Abstract

Al/porous silicon light emitting Schottky junctions for electroluminescent microdisplays are discussed. Bright light emission, visible by naked eye, is observed under reverse bias. The current level at which the EL starts is around 1 (mu) A for pixel area of 4 by 4 micrometers ² at applied voltages in the range of -5 V. The light emissions intensity increases with increasing of current density. EL spectra are broad, covering the whole visible range. The high time stability was observe for all tested devices: the EL intensity did not show considerable changes even after more than one month of continuous operation.
