Spectral photoconductivity measurements, performed in the 190 \u00f7 1100 nm wavelength range, returned an ultraviolet-to-visible (UV\/Vis) rejection ratio of 6.8 \u00d7 103 under photovoltaic operating conditions, ensuring solar blindness and zero power consumption at the same time. When applying bias, UV\/Vis rejection ratio reached excellent values (>104) even at very low electric fields (0.01 V\/?m), thanks to the excellent structural quality and the superior charge transport properties of the diamond bulk, as inferred from Raman analysis and spectral photoconductivity measurements. Mobility-lifetime (??) product of the photogenerated carriers was indeed measured to be about 5 \u00d7 10-3 cm2\/V in case of holes, which is the highest room-temperature ?? value ever reported for CVD diamond, enabling a response speed in the nanosecond range even at zero-bias operating conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Girolami Marco; Serpente Valerio; Mastellone Matteo; Tardocchi Marco; Rebai Marica; Xiu Qinglei; Liu Jinlong; Sun Zhijia; Zhao Yubin; Valentini Veronica; Trucchi Daniele M.<\/p>\n","protected":false},"featured_media":1294,"comment_status":"closed","ping_status":"open","template":"","meta":[],"product_cat":[574],"product_tag":[3793,3788,3789,3790,3791,3792],"class_list":["post-8860","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-journal-articles","product_tag-mobility-lifetime-product","product_tag-cvd-diamond","product_tag-uv-c-detectors","product_tag-self-powered-solar-blind-detectors","product_tag-asymmetric-schottky-contacts","product_tag-metal-semiconductor-metal-detectors","prodpage-style2"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product\/8860","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/comments?post=8860"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media\/1294"}],"wp:attachment":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media?parent=8860"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_cat?post=8860"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_tag?post=8860"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
