Schematic diagram of the proposed photodetector and its photoresponse and photoluminescence mapping (IMAGE)
Caption
a, Schematic illustration of the synthesis and structure of Ti3C2Tx MXene. b, Schematic diagram of the proposed PD prepared on the patterned sapphire substrate. c, high magnification (scale bar: 3 μm) optical images of the proposed PD. Inside the blue box is the finer area responsivity and photoluminescence mapping region. d, The responsivity mapping inside the blue box when the proposed PD at +5V bias (scale bar: 1 μm). The photoluminescence intensity mapping of the blue box region in Fig. 4b at the extracted Fabry-Pérot interference wavelengths of e 524.2 nm (trough), f 520.7 nm (peak), g 517.3 nm (trough) and h 513.1 nm (peak). The scale bar is 1 μm.
