Single crystals of CuxBi2Se3 (X=0, 0.1) topological insulator (TI) synthesized by using self –flux method and has been utilized for investigation room temperature humidity sensing study. The samples are thoroughly characterized XRD, FESEM, Raman, etc. Cu0.1Bi2Se3 single crystal exhibits highest sensitivity (∼276%), response/recovery time (∼25s.), negligible hysteresis (<1%) excellent stability within 8-97% RH range at temperature. Freundlich isotherm model shows improved adsorption...
Nanostructures of Bismuth Selenide (Bi2Se3), a 3D topological insulator material and Nickel (Ni) doped Bi2Se3 samples were prepared by hydrothermal method to explore the I-V characteristics.
