Title: | Tin compensation for the SnS based optoelectronic devices | Authors: | Wang, SF Wang, W Fong, WK Yu, Y Surya, C |
Issue Date: | 2017 | Source: | Scientific reports, 3 2017, v. 7, no. , 39704, p. 1-10 | Abstract: | In this paper we report the growth of high quality SnS thin films with good crystallinity deposited on two-dimensional (2D) mica substrates. It is believed that the 2D nature of SnS, with strong intra-layer covalent bonds and weak inter-layer van der Waals interactions, is responsible for its relative insensitivity to lattice mismatch. We also investigated the reduction of Sn vacancies in the material using Sn-compensation technique during the material growth process. The experimental results clearly demonstrated substantial enhancements in the electrical and structural properties for films deposited using Sn-compensation technique. A mobility of 51 cm2 V-1 s-1 and an XRD rocking curve full width at half maximum of 0.07° were obtained. Sn-compensated SnS/GaN:Si heterojunctions were fabricated and significant improvement in both the I-V characteristics and the spectral responsivities of the devices were characterized. | Publisher: | Nature Publishing Group | Journal: | Scientific reports | EISSN: | 2045-2322 | DOI: | 10.1038/srep39704 | Rights: | This work is licensed under a Creative Commons Attribution 4.0 International License.
