This work will describe the influence of molarity and time of potassium hydroxide etching on Al-rich AlGaN layer. With potassium hydroxide (KOH) molarity of 5 mol/L, no significant change on the pores formation was observed for 5 and 10 minutes of etching. Nonetheless, there was a possibilty that s...
