Title: Dean Ducharme: Innovator in Electroluminescent Device Technology
Introduction
Dean Ducharme is a notable inventor based in Ottawa, Canada. He has made significant contributions to the field of electroluminescent devices, particularly through his innovative patent that addresses key challenges in device reliability.
Latest Patents
Ducharme holds a patent for a light-emitting device with a stopper layer structure. This invention focuses on electroluminescent (EL) device structures that incorporate a hot electron stopper layer. The purpose of this layer is to capture hot electrons and dissipate their energy, which reduces damage to the transparent conducting oxide (TCO) layer. This innovation also mitigates other hot electron effects, such as charging effects, that can impact the reliability of EL device structures. The stopper layer can consist of a single layer or multiple layers positioned between the TCO electrode layer and the emitter structure. Additionally, it may help reduce diffusion or chemical interactions between the TCO and the emitter layer structure. The materials used for the stopper layer are typically wideband gap semiconductors or dielectrics, which are preferably transparent at the wavelengths emitted by the EL device and characterized by high impact ionization rates.
