Abstract EN
We report on the fabrication of porous GaAs (100) using three different acids, H2SO4, HF, and HCl, diluted in DMF based solutions.
The mixture of H2SO4 with DMF showed the best porous structures in comparison to other acids.
The concentration of the DMF solution was then varied for a fixed concentration of H2SO4.
It was apparent that the different concentration of the DMF solvent gave different types of morphology of the porous GaAs.
Furthermore, a higher current density improved the uniformity of the pores distribution.
The best porous GaAs exhibited well-defined circular shaped pores with high uniformity.
To the best of our knowledge, such structure produced in such manner has never been reported so far.
Finally, the optimum etching conditions of the pores were proposed.
