Lateral p-GaN/2DEG junction diodes by selective-area p-GaN trench-filling-regrowth in AlGaN/GaN

This work demonstrates a lateral p-n junction diode formed between the two-dimensional electron gas (2DEG) and the selective-area regrown p-GaN in AlGaN/GaN. Benefiting from the in-plane 2DEG channel, this p-GaN/2DEG diode can directly characterize the current conduction and voltage blocking characteristics of the regrown sidewall p-n ju...More
