This paper presents a self‐aligned heterojunction gate phototransistor that eliminates the need for high‐precision alignment tools. The device achieves a high responsivity of 2.9 × 105 A W−1 and a specific detectivity of 9.6 × 1013 Jones, comparable to the performance of non‐self‐aligned devices requiring complex fabrication.
