Patent number: 10269562Abstract: The invention provides the use of at least one binary group 15 element compound of the general formula R1R2E-E?R3R4 (I) or R5E(E?R6R7)2 (II) as the educt in a vapor deposition process. In this case, R1, R2, R3 and R4 are independently selected from the group consisting of H, an alkyl radical (C1-C10) and an aryl group, and E and E? are independently selected from the group consisting of N, P, As, Sb and Bi. This use excludes hydrazine and its derivatives. The binary group 15 element compounds according to the invention allow the realization of a reproducible production and/or deposition of multinary, homogeneous and ultrapure 13/15 semiconductors of a defined combination at relatively low process temperatures. This makes it possible to completely waive the use of an organically substituted nitrogen compound such as 1.Type: GrantFiled: September 25, 2015Date of Patent: April 23, 2019Assignee: PHILIPPS-UNIVERSITÄT MARBURGInventors: Carsten Von Haenisch, Kerstin Volz, Wolfgang Stolz, Eduard Sterzer, Andreas Beyer, Dominik Keiper, Benjamin Ringler

Patent number: 5057881Abstract: A multiple quantum well light emitting compositional semiconductor device ch as a laser diode or a light emitting diode has an active region comprising an alternating sequence of layers of well layer material and of barrier layer material. The thickness of the barrier layer and of the adjacent well layers is chosen such that for one type of charge carrier a relatively high probability exists for such charge carriers to be present in the barrier region whereas the other type of charge carriers are localized in the potential wells. In this way it is possible to reduce the probability of non-radiative Auger recombination processes occurring thus reducing the threshold current and increasing the quantum efficiency of the device.Type: GrantFiled: November 30, 1989Date of Patent: October 15, 1991Assignee: Max-Planck Gesellschaft zur Forderung der Wissenschaften e.V.Inventors: Hans Lobentanzer, Wolfgang Stolz, Klaus Ploog, Julien Nagle
