ACHIEVMENTS

By thermal CVD method, single-walled CNTs, double-walled CNTs, graphene, graphene/CNTs, CNTs/MoS₂, and graphene/MoS₂ materials were successfully fabricated on copper and SiO₂/Si substrates.
Application of graphene, graphene/CNTs material in electrochemical sensor for detection of toxic substances (glyphosate, carbaryl, and other heavy ion metals such as arsenic, lead, etc).
Preparing solar panels of (SiNW/PEDOT:PSS/Gr) hybrid material. These panels have power conversion efficiency of about 9.05%, which is about 2.1 times higher than that of the planar Si solar cell.
