| 中文摘要 | We have observed ultraviolet photosensitive properties of SrTiO3 single crystals. The photoresponse signal reaches 7.6 mV under a bias voltage of 110 V and an on-sample energy of 250 nJ for a 15-ps-duration 355 nm laser pulse. A linear relationship is obtained to the peak signal as a function of bias without any saturation trend from 1 to 110 V. Ultrafast characteristic as a function of time was also presented with the rise time as short as 750 ps. Furthermore, a weak photoresponse was detected with a large bias of 2.5 kV under a 420-nm-wavelength laser pulse due to band edge tilting, and drop three orders of magnitude than that under the 355 nm laser pulse, indicating the setup consisting of SrTiO3 single crystal is suitable for detecting ultraviolet radiation. |
