Semiconductor light emitting element having barriers which prevent forward current in a semiconductor film thereof
Abstract:
A semiconductor light emitting element of the present invention includes a support substrate, a semiconductor film including a light emitting layer, a surface electrode provided on the surface on a light-extraction-surface side of the semiconductor film, and a light reflecting layer. The surface electrode includes first electrode pieces that form ohmic contact with the semiconductor film and a second electrode piece electrically connected to the first electrode pieces. The light reflecting layer includes a reflecting electrode, and the reflecting electrode includes third electrode pieces that form ohmic contact with the semiconductor film and a fourth electrode piece electrically connected to the third electrode pieces and placed opposite to the second electrode piece. Both the second electrode piece and the fourth electrode piece form Schottky contact with the semiconductor film so as to form barriers to prevent forward current in the semiconductor film.
