WebJul 31, 2024 · Systematic characterization measurements have verified good uniformity and sharp interfaces of the channel materials. As a result, the photodetectors enhanced by the photogating effect can deliver competitive performance, including responsivity of ~ 567.6 A/W and detectivity of ~ 7.17 × 10 11 Jones. In addition, the 1/f noise obtained from the ... WebWhen the transistor is on, the photogating effect was considered as a main mechanism of photocurrent generation. There are two causes for photogating effect; One is a gating effect from captured carriers on trap state, and the other is from keeping charge neutrality resulting from the difference of electron and hole mobilities.
