摘要: Abstract A detailed simulation on the intersubband absorption for 1–2, 2–3, and 1–3 optical transitions in ZnO/MgxZn1−xO quantum wells is presented. The quantum-confined Stark effect induced by internal polarization field process effectively controlled through an external electric field. It easy to obtain structural optimization of light different terahertz ranges our numerical analysis. wavelengths corresponding almost all increase as applied varies from −500 kV/cm 500 kV/cm. small coefficient transition increased enhancing asymmetry quantum-well potential. present work can be extended design new optoelectronic devices based other low-dimensional structures such wires dots.
