Low-cost Growth of Magnesium Doped Gallium Nitride Thin Films by Sol-Gel Spin Coating Method
Low-cost sol-gel spin coating growth of magnesium (Mg) doped gallium nitride (GaN) thin films with different concentrations of Mg was reported. The effects of the Mg concentration on the structural, surface morphology, elemental compositions, lattice vibrational, and electrical properties of the dep...
