Currently, a semiconducting Si-based transistor is used as a biosensor. However, since the bandgap of Si is only 1.1 eV, the operation becomes unstable when exposed to deep ultraviolet such as a germicidal lamp while the transistor is operating. The research team worked on the development of a thin film transistor using the oxide semiconductor strontium stannate as the active layer, which has a large bandgap of 4.6 eV. Transistors obtained by optimizing the combination of materials not only show clear transistor characteristics but also transmit deep UV light with a wavelength of 260 nm by 50% or more when there are no gate electrodes. The deep-UV transparent transistor would be expected as a prototype of a novel biosensor that operates even when it is exposed to the deep UV of a germicidal lamp.<\/p>\n<p><strong>Original article<\/strong><\/p>\n<p>Mian Wei, Lizhikun Gong, Dou-dou Liang, Hai Jun Cho*, and Hiromichi Ohta*, \u201cFabrication and Operating Mechanism of Deep-UV Transparent Semiconducting SrSnO<sub>3<\/sub>-based Thin Film Transistor\u201d, <em>Advanced Electronic Materials<\/em> <strong>6<\/strong>, 2000100 (2020).
