Latest Patents
Julien Nagle holds a patent for a "Light Emitting Compositional Semiconductor Device." This invention describes a multiple quantum well light-emitting device, such as a laser diode or a light-emitting diode. The active region of this device comprises an alternating sequence of layers of well layer material and barrier layer material. The design allows for a high probability of charge carriers being present in the barrier region while localizing the other type of charge carriers in the potential wells. This innovative approach reduces the probability of non-radiative Auger recombination processes, thereby lowering the threshold current and increasing the quantum efficiency of the device. This is particularly crucial for material systems with a small bandgap that operate at long wavelengths suitable for optical fiber transmission.
