Surface patterning of wide-gap semiconducting β-Ga2O3 thin films by area selective crystallization via room-temperature excimer laser annealing and low-toxic wet etching processes

In the present study, we have developed a fully room-temperature and low-toxic surface patterning method for β -Ga _2 O _3 , which consists of the area selective laser-induced crystallization of amorphous Ga _2 O _3 thin films and acid solution etching processes. Highly ( $\bar{2}$ 01)-oriented crys...
