Description
β-Gallium Oxide (Ga 2 O 3 ), the most stable phase of Ga 2 O 3 , is a semiconductor with an ultra-wide bandgap and has applications in high power electronic devices. In this study, we investigated the impact of Gallium beam flux on the surface roughness in order to maximize the growth rate of Ga 2 O 3 . The Ga 2 O 3 films were grown by plasma-assisted molecular beam epitaxy (MBE) and were characterized using atomic force microscopy (AFM). Five samples were grown and measured. The beam flux for these samples were: 1.6 × 10 -7 , 8.0 × 10 -8 , 4.0 × 10 -8 , 3.0 × 10 -8 ,and 2.0 × 10 -8 Torr. With the exception of the first sample, our results convey a decrease of surface roughness with the decreasing Gallium beam flux.
