Outline of Final Research Achievements |
In order to realize flow-assisted-mode liquid phase epitaxy of GaN, the following processes were pursuit; design and trial fabrication of boat by the aide of 3D printer, modification of normal LPE system, optimization of growth conditions. With mechanically generated a convection in the solution by a rotating wheel, it was succeeded in a very flat and uniform growth of GaN layer with the growth rate of 0.5 um/h under atmospheric pressure without using any additives in the solution. At the same time, we have succeeded in a very-flat lateral growth of c-plane GaN by liquid phase electro epitaxy by using mesa-shaped GaN template substrate. The growth of the very-wide and flat GaN layer was successfully obtained to combine the adjoining laterally grown layers.
