Title: The Innovations of Pierre Ferret
Introduction
Pierre Ferret is a notable inventor based in Grenoble, France. He has made significant contributions to the field of optoelectronics, holding a total of 8 patents. His work focuses on advanced semiconductor structures that enhance the performance of optoelectronic devices.
Latest Patents
One of his latest patents is an optoelectronic device comprising three-dimensional semiconductor structures with a wider single-crystal portion. This invention relates to an optoelectronic device that includes at least one microwire or nanowire extending along a longitudinal axis substantially orthogonal to a substrate plane. The device features a first doped portion made from a first semiconductor compound, an active zone extending from this portion, and a second doped portion that partially covers the active zone. The active zone is characterized by a wider single-crystal portion formed of a second semiconductor compound and at least one additional element, extending from the upper face of the first doped portion.
Another significant patent is for a multiple quantum well light-emitting device. This device includes a substrate and three-dimensional semiconductor elements resting on it. At least one shell partially covers the lateral walls of the semiconductor element, and the shell contains an active area with multiple quantum wells. An electrode partially covers the shell, with a portion of the active area sandwiched between the electrode and the lateral walls of the semiconductor element. The active area consists of alternating semiconductor layers that include various elements, with the mass concentration of a third element increasing as the distance to the substrate decreases.
