OPTOELECTRONIC SEMICONDUCTOR STRUCTURE AND METHOD FOR TRANSPORTING CHARGE CARRIERS

摘要

An optoelectronic semiconductor structure (20) comprises an n-type semiconductor region (3); a p-type semiconductor region (1); a p-n junction formed between the n-type and p-type semiconductor regions; and an active region (2). According to the present invention, the optoelectronic semiconductor structure (20) is configured to transport, when in use, charge carriers between the active region (2) and each of the re¬ type semiconductor region (3) and the p-type semiconductor region (1) through a single substantially planar boundary surface (9) of the active region.
