Latest Patents

Carmel Sahar holds a patent for a "Gallium nitride based ultra-violet sensor with intrinsic amplification and method of operating same." This UV sensor features a GaN stack that includes a low-resistance GaN layer formed over a nucleation layer, and a high-resistance GaN layer formed over the low-resistance GaN layer. A two-dimensional electron gas (2DEG) conductive channel exists at the upper surface of the high-resistance GaN layer. The design incorporates an AlGaN layer over the high-resistance GaN layer, with source and drain contacts that extend through the AlGaN layer to electrically couple to the 2DEG channel. The sensor's functionality is based on the electrical current between the source and drain contacts, which varies according to the UV light received by the GaN stack. An electrode connected to the low-resistance GaN layer allows for electrical refresh of the UV sensor. This innovative design has the potential to enhance UV detection capabilities significantly.
