Abstract:Photothermal effects have recently been widely investigated for applications in the fields of biomedicine, physics, and chemistry. Unfortunately, only a few reports describe their potential use in ultrafast photodetectors. Herein, direct evidence for ultrafast photothermal‐induced electrical behavior of a platinum microwire (Pt MW) illuminated by a focused laser beam and modulated at different frequencies (329 Hz, 10, 50, and 150 kHz) is provided. The obtained electrical behavior images indicate that Pt‐based … Show more
