Open Circuit Voltage Photodetector
TS-065426 — Photodetectors are devices that detect light and convert it into an electrical signal. They operate based on the photoelectric effect, in which photons (light particles) strike the semiconductor material, creating electron-hole pairs that lead to the flow of electrical current that can be measured.
Existing photodetectors are susceptible to various noise sources, such as thermal and electronic. The noise can degrade the signal-to-noise ratio and affect the accuracy of measurements, particularly in low-light conditions.
This technology is an open-circuit voltage photodetector (OCVP) that…

Monolithically Integrated Tunnel Junction-Based GaN Light Emitting Transistors
TS-065398 — Emissive display technologies (e.g., OLEDs) are display technologies that emit light directly to produce images. Unlike reflective displays, which rely on external light sources, emissive displays generate light, resulting in vibrant and high-contrast visuals. These next-generation displays are used in several applications, including mobile devices, AV/VR headsets, and wearable devices.
Although emissive displays are integrated into many electronic devices, they face some challenges. One of the primary issues is the integration of LEDs and electronic drivers when scaling into mesa dimensions. The mesa is a crucial parameter in display manufacturing as it determines the size of th…

Surface barrier engineering using AlGaO/GaO
TS-063001 — A new method of surface barrier engineering that introduces a linearly graded (AlxGa1-x)2O3 cap layer. This improves the Schottky barrier at the surface which results in a higher breakdown field.
Ga2O3 is a promising ultra-widebandgap semiconductor with many applications in power switching and RF electronics. Realizing those improvements requires efficient field management design to prevent premature breakdown due to electric field crowding at the device edges. There is a need to develop t…
