Terahertz emission from gradient InGaAs surfaces Article uri icon

abstract

  • We present an experimental study of the terahertz emission from InxGa1−xAs epitaxial layers that were grown while varying the alloy fraction x. We observe the terahertz emission that is significantly different depending on the variation direction of the alloy fraction. We attribute the difference to the significant change of the band bending induced in the growth direction and to the position-dependent variation of the effective mass. © 2021 Author(s).
