“…3c). The phenomenon of opposite changing trend between photoresponsivity and optical power can be attributed to the increase of carrier recombination rate following a higher optical power, which makes this device applicable for the detection of weak DUV signals [30], [31]. Besides, it can be observed from Fig.…”

In this work, a low-temperature solution process is proposed to synthesize Lu 2 O 3 films with few surface defects for the purpose of fabricating high-performance deep-ultraviolet (DUV) detectors. Based on the solutionprocessed Lu 2 O 3 film treated at 250 • C, a high-sensitivity Lu 2 O 3 /GaN DUV photovoltaic detector is fabricated, which has exhibited excellent performance in many aspects. At 0 V bias voltage, it displays a peak photoresponsivity of 41.6 mA/W at 258 nm and a DUV to visible rejection ratio (R 258 nm /R 405 nm ) higher than two orders of magnitude. What's more, compared with devices based on high-temperature (500 • C) solution-processed (H-T) Lu 2 O 3 film, the device prepared in this way shows a greater photoresponsivity and a response speed faster than an order of magnitude, which can be attributed to the fewer surface defects aroused during the low-temperature solution process. The great characteristics achieved suggest the Lu 2 O 3 film treated by the method of low-temperature solution process can be applied to fabricating high-performance DUV detectors.

“…4(c). The specific detectivity ( D *) is another important feature of photodetectors, which can be described as follows: 44–46 where A , B , R and denote the effective area ( A = 2.0 × 10 −3 cm 2 ), the bandwidth, the responsivity, and the root-mean-square value of the noise current, respectively. The root-mean-square noise current measured at the bandwidth of 1 Hz is ∼0.87 nA Hz −1/2 (Fig.…”
