    • Abstract


      Polycrystalline SbAs nanorods were synthesized by the simple solvothermal method. X-ray diffraction analysis of prepared SbAs confirmed the formation of rhombohedral structure and the average crystallite size of ${\sim}$9 nm. Nanorods shaped morphology of SbAs polycrystalline was studied using high-resolution scanning electron microscopy analysis. The optical bandgap energy of 3.58 eV was determined from UV–visible spectrum with absorption maximum at 226 nm. An uncommon and fascinating potential-induced semiconductor to insulator-like transition is determined within the frequency-dependent real and imaginary part of impedance, dielectric plot and modulus plot. The direct bandgap of prepared SbAs nanorods made it applicable in opto-electronic devices.
