The CdS nanobelt was synthesized by the vapor phase transportation (VPT) method. X-Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM) results revealed that the nanobelt had a hexagonal wurtzite structure of CdS and presented good crystal quality. A single nanobelt Schottky contact optical sensor was fabricated by the electron beam lithography (EBL) technique, and the device current-voltage results showed back-to-back Schottky diode characteristics. The photosensitivity, dark current and the decay time of the sensor were 4 \u00d7 104, 31 ms and 0.2 pA, respectively. The high photosensitivity and the short decay time were because of the exponential dependence of photocurrent on the number of the surface charges and the configuration of the back to back Schottky junctions.<\/jats:p>","DOI":"10.3390\/s140407332","type":"journal-article","created":{"date-parts":[[2014,4,23]],"date-time":"2014-04-23T12:29:40Z","timestamp":1398256180000},"page":"7332-7341","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Optical Sensor Based on a Single CdS Nanobelt"],"prefix":"10.3390","volume":"14","author":[{"given":"Lei","family":"Li","sequence":"first","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi'an Jiaotong University,  Xi'an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuming","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi'an Jiaotong University,  Xi'an 710049, China"},{"name":"State Key Laboratory of Digital Manufacturing Equipment & Technology, Huazhong University  of Science and Technology, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Han","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi'an Jiaotong University,  Xi'an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liangjun","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi'an Jiaotong University,  Xi'an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaotong","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi'an Jiaotong University,  Xi'an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhuangde","family":"Jiang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi'an Jiaotong University,  Xi'an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anlian","family":"Pan","sequence":"additional","affiliation":[{"name":"Key Laboratory for Micro-Nano Optoelectronic Devices of Ministry of Education, School of Physics and Microelectronics, Hunan University, Changsha 410082, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2014,4,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1887","DOI":"10.1021\/nl060867g","article-title":"Photoconductive characteristics of single-crystal CdS nanoribbons","volume":"6","author":"Jie","year":"2006","journal-title":"Nano Lett."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"69","DOI":"10.1016\/j.cplett.2009.06.007","article-title":"Novel fabrication of UV photodetector based on ZnO nanowire\/p-GaN heterojunction","volume":"476","author":"Chen","year":"2009","journal-title":"Chem.
