However, in the literature, such figures of merit (FoM) are typically extracted in stationary conditions, very often from IV curves taken under constant light exposure. In this work, we studied the most relevant FoM of a DNTT-based organic phototransistor as a function of the timing parameters of light pulses, to assess the device suitability for real-time applications. The dynamic response to light pulse bursts at ~470 nm (close to the DNTT absorption peak) was characterized at different irradiances under various working conditions, such as pulse width and duty cycle. Several bias voltages were explored to allow for a trade-off to be made between operating points. Amplitude distortion in response to light pulse bursts was also addressed.<\/jats:p>","DOI":"10.3390\/s23052386","type":"journal-article","created":{"date-parts":[[2023,2,22]],"date-time":"2023-02-22T02:08:34Z","timestamp":1677031714000},"page":"2386","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Dynamic Photoresponse of a DNTT Organic Phototransistor"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2518-7134","authenticated-orcid":false,"given":"Marcello","family":"Campajola","sequence":"first","affiliation":[{"name":"Istituto Nazionale di Fisica Nucleare (INFN), Sezione di Napoli, Via Cintia, 80126 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Di Meo","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Fisica Nucleare (INFN), Sezione di Napoli, Via Cintia, 80126 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Di Capua","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Fisica Nucleare (INFN), Sezione di Napoli, Via Cintia, 80126 Napoli, Italy"},{"name":"Department of Physics \u201cE.
