Charge Transfer Properties of Surface-treated WS2 Nanotubes and Fullerene-like Nanoparticles

Abstract

We studied the effect of incorporation of inorganic fullerene like nanoparticles (IF) and inorganic nanotubes (INT) of WS2 into device structures. In order to disperse in a uniform fashion the semiconducting INT/IF WS2 nanoparticles were functionalized with dodecyltrichlorosilane (DTS). Poly-3(hexylthiophene) (P3HT) has been used along with WS2 nanoparticles as an active layer for the solution processable material in the proposed OLED structure of the type: ITO/WS2/P3HT/LiF-Al to test the electrical effect of the WS2 and to obtain information on its energy levels. Based on the obtained results, we discuss the possibility to use the WS2 nanoparticles in organic electronic devices.
