Structural, Optical and Electrical Characterization of CdSe Nanorods Synthesized by Solvothermal Process

Abstract

CdSe is a direct band gap II–VI compound semiconductor, which can exist in both zinc blende phase and wurtzite phase. Its direct band gap of 1.7 eV divides the solar spectrum into two parts, namely, the “thermal” part with ℎ] < 𝐸 𝑔 and the “optical” one with ℎ] > 𝐸 𝑔, both parts with practically equal radiation energy.
