Introduction

Jonathan Wierer is an accomplished inventor based in Albuquerque, NM (US). He has made significant contributions to the field of ultraviolet light-emitting diodes (LEDs). His innovative work focuses on enhancing the efficiency of these devices, which are crucial for various applications in lighting and technology.

Latest Patents

Wierer holds a patent for a "High extraction efficiency ultraviolet light-emitting diode." This invention utilizes tailored AlGaN quantum wells to achieve high extraction efficiency. The design favors parallel polarized light for efficient bottom light extraction, as it propagates predominantly perpendicular to the quantum well plane. This approach is more effective than perpendicular polarized light, which requires multiple, lossy bounces before extraction. The thickness and carrier density of AlGaN quantum well layers significantly influence the valence subband structure, optical polarization, and light extraction efficiency of ultraviolet LEDs. Specifically, at Al>0.3, thinner quantum well layers (less than 2.5 nm) are preferred to achieve light that is preferentially polarized parallel to the quantum well plane.
