Comparison of Optoelectronic Properties of Doped and Pristine Nanotubes Based on Carbon and Tungsten Disulfide

: The optoelectronic properties of one-dimensional nanomaterials play an important role in electronic devices. In the present work, pristine and doped Carbon Nanotubes (CNTs) and WS 2 Nanotubes (WS 2 NT) are investigated by using absorption, Raman, and THz time-domain spectroscopy (THz-TDS). We demonstrate that the one-dimensional materials share similar properties asso-ciated with curvature and location in comparison with two-dimensional materials. In addition, we show how doping influence to these properties. Our results pave the way toward the application of such materials as a prospective material for optoelectronic devices including future wireless com-munication devices.
