Tailoring of physical properties of glassy selenium (g-Se) by using multi-walled carbon nanotubes (MWCNTs)

•Synthesis of novel nanocomposite by using glassy Se (g-Se) and MWCNTs.•The electrical conductivity of g-Se is enhanced drastically after MWCNTs doping.•MWCNTs play important role in improving the hardness of g-Se.•The resistive switching behavior is also changed dramatically after doping of MWCNTs.
